This essay Lipids has a total of 498 words and 3 pages.
The subject I will cover is lipids. I will tell you about the description of it’
s organic compound. I will tell you where it is found. I will tell you what
the uses are in plants and animals. I will also tell you about it’s chemical
structure and give examples of types of these compounds, such as cholesterol.
The organic compound of lipids have many similarities. They are almost always
greasy, fatty, oily, or waxy. They do not dissolve in water, but they do in
other organic solvents. This is like if you get grease on your hands it is hard
to wash of because it seems to repel the water.
You can find lipids in many places. They are usually in fatty foods like butter,
salad dressing, and cooking oils. They can also be found inside of animals as
the form of fat. Lipids are always found in fat because when you get a build up
of lipids it forms fat.
Lipids have many uses amongst plants and animals. The main use of these are for
energy and storing energy. When they store energy they make triglycerides also
known as fat. There are also many other uses such as insulation and protection.
They are also used in making cell membranes. They make it so that the cell can
maintain it’s shape by keeping water and water-soluble compounds from passing
through it. The lipids that are waxy are usually used to make protective
coatings on the surface of plants and animals.
Since a lipid is an organic compound it contains carbon. They also contain
hydrogen and oxygen, but in some very complex chains there is also phosphorus
and/or nitrogen. Lipids are made by the dehydration synthesis of glycerol and
fatty acids. This is when three molecules of fatty acids combine with one
molecule of glycerol by taking water out of the solution. Lipids are always
huge molecules, which means they have a lot of energy like twice as much as
sugar. This is because more energy goes into making it so you get more out of
it when it is broken down. The following is what a lipid would look like.
When lipids are made they can produce many different compounds. One of those is
phospholipids. These are what help make cell membranes and keep water out of
them. They also make a very common lipid and that is cholesterol. Cholesterol
is and extremely complex lipid. It builds up on the inner walls of the arteries.
If it is built up in large amounts it can cause high blood pressure and
increase the risk of heart attacks. If this occurs than you must change your
diet and exercise to decrease the amount of cholesterol you have. Sometimes
high cholesterol levels are passed genetically and you can’t do much about it.
In this report I’ve covered the following information on lipids:
1. What the organic compound is like. 2. Where they are found. 3. What the
animals and plants use them for. 4. What the chemical makeup is. 5. I’ve also
given examples of types of compounds. 6. Explained what cholesterol is.
The Cheese We EatThe Cheese We Eat The Cheese We Eat Cheese sticks, cheese lasagna, cheesecake, cheese and broccoli, cheeseburger, cheese quiche, cheese omelet, goat cheese, cheddar cheese, Swiss cheese, blue cheese, parmesan cheese, ... the list goes on and on. However, despite the abundance of cheese in the food we eat it often goes unnoticed. Cheese is an under rated food that deserves more recognition than it gets. Cheese is a food that has been around for years, it is very abundant, and above all, cheese
Dietary Guidelines for North Americans and SuggestDietary Guidelines for North Americans and Suggestions for Food Choices In today\'s society nearly everyone follows some kind of dietary guidelines. Whether it is in the goal of losing weight, gaining weight or just simply to maintain it, people are jumping onto the dietary band-wagon. A diet is basically to take food according to rule, a mode of living in reference to nourishment. There are various types of diets that one can follow; a high or low calorie diet, low fat diets, diets modified in
Diverrsity of PlantsDiverrsity of Plants Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago, trees had evolved and formed forests, within which the diversification of vertebrates, insects, and fungi occurred. Roughly 266,000 species of plants are now living. The two major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes and ferns require free water so that sperm can swim

Bone DiseasesBone Diseases Bone diseases most directly influence the ability to walk or to move any part of the body--hands, limbs, neck, and spine. They are related to joint disorders--ARTHRITIS, COLLAGEN DISEASE, DISLOCATION of joints, and RHEUMATISM. The medical specialty pertaining to bone disorders is ORTHOPEDICS. Fractures are the most common bone disorders. They can occur as the result of an accident or be secondary to metabolic diseases. Fractures are life-threatening to aged people having the metabo
NutritionNutrition “You are what you eat”, goes a famous saying. If that’s truly the case, then a lot of Americans would appear to be unhealthy, chemically treated, commercially raised slabs of animal flesh. While that is not a particularly pleasant thought, it is nonetheless a description of the typical American omnivore who survives on the consumption of big macs and greasy french fries. It’s true, and what have the average Americans done about this problem? Asked for seconds and tell themselves that t
PlantsPlants The four kinds of plants Plants are the link of the evolutionary chain that helped start life as we know it. Some 700 million years ago we had their first ancestors, algae, developed in the seas, 265 million years after that the first simple stalked plants we found outside the seas now but along their coasts and along streams (Starr, C. Taggart, R. pp.153). Through out the years plants have evolved to the ones we know today and can differentiate them by the following categories: Nonvascul
BoronBoron Boron is in group 13 (or IIIa) of the periodic table. The pure element was first prepared in 1808 by the French chemists Joseph Gay-Lussac and Baron Louis Thénard, and independently by the British chemist Sir Humphry Davy. It is a trace element needed for plant growth, but can be deadly if used in excess. Research suggests that it is also nutritionally important for bone health in humans and other vertebrates. Pure boron is a powder. Boron melts at about 2180° C, boils at about 3650° C, an
DIETDIET Because the human diet is typically diverse, human beings are classified as omnivores rather than as herbivores (plant eaters) or carnivores (meat eaters). Certain groups of people do derive most of their food from animal sources--for example, the traditional Inuits of the Arctic region and the Masai of Africa--while other people practice vegetarianism. By far the majority of humankind, however, eats a wide range of foods of both animal and vegetable origin. Prehistoric humans were hunters
AlcoholismAlcoholism Alcoholism, chronic and usually progressive illness involving the excessive inappropriate ingestion of ethyl alcohol, whether in the form of familiar alcoholic beverages or as a constituent of other substances. Alcoholism is thought to arise from a combination of a wide range of physiological, psychological, social, and genetic factors. It is characterized by an emotional and often physical dependence on alcohol, and it frequently leads to brain damage or early death. Some 10 percent

TREATMENTS OF ALCOHOLISM Alcoholism can destroy the life of an alcoholic and devastate the alcoholic\'s family. But it also has overwhelming consequences for society. Consider these statistics from the National Council on Alcoholism and Drug Dependence: *In 1988, alcoholism and problems related to it cost the United States an estimated $85.8 billion in mortality and reduced productivity; *Fetal alcohol syndrome, caused by a woma
VegetarianismVegetarianism 10/9/96 Vegetarianism The time that we are now living in has been termed by many as the information age. This title has been given to the current era because people can retrieve, send, and process knowledge faster and more efficiently than ever before. From our new period has come technological advancements which have both caused and been an effect of the growing pool of information available to the world. Communities more fully understand and are changing the way they affect the e
American Home Products: A Pharmaceutical EmpireAmerican Home Products: A Pharmaceutical Empire History of American Home Products American Home Products Corporation (AHP) was founded in 1926 and has a history of continuous acquisitions of smaller companies that made proprietary medicines. In 1931, AHP purchased John Wyeth Brother, Inc. from Harvard University. Another important acquisition was that of Canada’s Ayerst Laboratories in 1943. Ayerst was a large pharmaceutical company that had introduced Premarin, the world’s first conjugated estr
Robinson CrusoeRobinson Crusoe Robinson was a young man of 18 and had a dream to be a sailor. He asked his father for permission. His father thought that he should stay home and take over the family business or study law. Robinson asked his father again to let him have just one sail. His father disapproved once more. One afternoon a shipped sailed in from the harbor. The captain of the ship was one of Crusoe’s friend’s, father. The captain invited Crusoe on a voyage to the English coast and he couldn’t resist.
Population And FoodPopulation And Food The United Nations projects that the global population, currently at 6 billion, will peak at about 10 billion in the next century and then stabilize or even decline. (popindex.Princeton.edu) A question immediately following the statement, can the Earth feed that many people? It is understood that even if food crops increase sufficiently, other renewable resources, including many fisheries and forests, are already under pressure. Our food production doubled from 1961 to 1994,
Beta CaroteneBeta Carotene Beta-carotene is a member of the carotenoid family and has over 500 relatives. Carotenoids are yellow-to-red pigments found in all green plant tissues and in some species of algae. So far 21 different carotenoids have been found in human blood. The most abundant ones are alpha-carotene, beta-carotene, lutein, lycopene, cryptoxanthin and zeaxanthin. A molecule of alpha-carotene, beta- carotene, or cryptoxanthin can be split into two molecules of vitamin A in the body but the convers
Inflammatory Bowel Disease/ Crohn's DiseaseInflammatory Bowel Disease/ Crohn\'s Disease Inflammatory bowel disease (IBD) is a group of chronic disorders that cause inflammation or ulceration in the small and large intestines. Most often IBD is classified as ulcerative colitis or Crohn\'s disease but may be referred to as colitis, enteritis, ileitis, and proctitis. Ulcerative colitis causes ulceration and inflammation of the inner lining of a couple of really bad places, while Crohn\'s disease is an inflammation that extends into the deep
Food ProcessingFood Processing Throughout the history of mankind science has searched into the realms of the unknown. Along with it bringing new discoveries, allowing for our lives to become healthier, more efficient, safer, and at the same time, possibly more dangerous. Among the forces driving scientists into these many experiments, is the desire to preserve the one fuel that keeps our lives going; FOOD. As early as the beginning of the 19th century, major breakthroughs in food preservation had begun. Soldie

Anabolic SteroidsAnabolic Steroids Anabolic steroids are synthetic coumpounds formulated to be like the male sex hormone testosterone. Many athletes use anabolic steroids male and female alike, such as body builders , weightlifters, baseball players, football players, swimmers, and runners. They do so because they mistakenly believe that they will gain strength and size. In a male testosterone is released by the leydig cells in the testes. The testosterone has two main functions androgenic and anabolic. Androgen
Birth DefectsBirth Defects No one is immune to birth defects, yet not everyone is equally susceptible. Birth defects are not merely a medical problem. They have profound effects on the social and psychological well being of their family and friends. In the normal course of fetal development, cells migrate to their appropriate destination so that organs and limbs form where they should. Usually, the genes perform flawlessly, but mistakes can and do occur. Some of the most common birth defects results from the
Genetic Diversity In AgricultureGenetic Diversity In Agriculture Genetic variation is the raw material for the plant breeder, who must often select from primitive and wild plants, including wild species, in search of new genes. The appearance of new diseases, new pests, or new virulent forms of disease causing organisms makes it imperative that the plant be preserved, because it offers a potential for the presence of disease resistant genes not present in cultivated varieties. Also, there are demands for new characters-- for e
Genetic EngineeringGenetic Engineering Bioengineering, or genetic engineering is an altering of genes in a particular species for a particular outcome. It involves taking genes from their normal location in one organism and either transferring them elsewhere or putting them back into the original organism in different combinations. Most biomolecules exist in low concentrations and as complex, mixed populations which it is not possible to work efficiently. This problem was solved in 1970 using a bug, Escherichia co

Birth DefectsBirth Defects Birth defects, or congenital malformations, are the faulty formation of structures or body parts present at birth. Sporadic, hereditary, or acquired defects may be immediately observed or may become manifest later in life; they may be visible on the body surface or present internally. Birth defects may be life threatening and require surgical correction, or they may interfere with function or appearance. It is estimated that about 3% of all children are born with major defects; min
BlindnessBlindness The term blindness implies total or partial loss of vision involving both eyes. The exact level of vision defined as blindness, however, varies in different countries because of differing legal or social requirements. In the United States, blindness is defined as unimprovable vision of 20/200 (6/60) or worse. This means that an individual is generally considered blind who, even with the use of ordinary eyeglasses, can see no better at 20 ft (6 m) than a person with normal vision can se

On any given day in the United States... 10,657 baFAS On any given day in the United States... 10,657 babies are born. (US Census Bureau). Twenty of these babies are born with Fetal Alcohol Syndrome. Twenty may seem as though it is not a lot, but when you compare it to the fact that this number is more than HIV positive, Muscular Dystrophy, Spina Bifida and Down Syndrome combine it creates a whole new parameter. Fetal Alcohol Syndrome is a direct result of a woman’s competed disregard for the fetus. Fetal Alcohol Syndrome (FAS, hereinafter), is
Fluids and HydrationFluids and Hydration How important are fluids? Fluid replacement is probably the most important nutritional concern for athletes. Approximately 60% of your body weight is water. As you exercise, fluid is lost through your skin as sweat and through your lungs when you breathe. If this fluid is not replaced at regular intervals during exercise, you can become dehydrated. When you are dehydrated, you have a smaller volume of blood circulating through your body. Consequently, the amount of blood you
Genetic Modified FoodGenetic Modified Food Genetic modification of organisms in general is a biotechnological process that forces genes to behave according to certain characteristics. Changing characteristics of organisms is based on changing their DNA (tech deoxyribonucleic acid; the acid which carries genetic information in a cell). It is being used for modifying genes in plants, animals or micro-organisms. It is being also used especially with food in order to improve the nutritious quality, make less use of chem

Vegetarianism - To Meat Or Not To MeatVegetarianism - To Meat Or Not To Meat As children, one of the first things we learn is to recognize the friendly barnyard animals. We easily can spot the furry cow with the gentle eyes, the feathery chickens who run wildly about, and the pink pigs that roll in the mud. We may also sing about that nice farmer, Old McDonald, and all of his nice animals. The truth is that Old McDonald with a straw hat has been replaced by a business man in the hard hat. Ninety-five percent of the meat we eat does

Mark Overman On CreatineMark Overman On Creatine Mark Overman on Creatine By. Mark D. Overman Creatine is one of the primary things an athlete will do to put supplements into their body. These supplements range from protein shakes to illegal anabolic steroids. Some sports supplements are incredibly safe and effective, yet others work for a while and then fizzle out, while others still work well but do more damage than good in the long run. In the past athletes had to turn to such things as anabolic steroids or blood do
Eating DisordersEating Disorders An eating disorder is a way of using food to work out emotional problems. These illnesses develop because of emotional and/or psychological problems. Eating disorders are the way some people deal with stress. In today’s society, teenagers are pressured into thinking that bring thin is the same thing as being happy. Chemical balances in the brain that may also result in depression, obsessive compulsive disorders, and bi-polar disorders may also cause some eating disorders. Other

Signs of StressSigns of Stress Forty-three percent of all adults suffer adverse health effects from stress; 75 to 90 percent of all physician office visits are for stress-related ailments and complaints; stress is linked to the six leading causes of death--heart disease, cancer, lung ailments, accidents, cirrhosis of the liver, and suicide. (Miller, 1993, p.12) Stress plays havoc with our health, our productivity, our pocketbooks, and our lives, but it is necessary, even desirable. (Oxford, 1998, p.29) In rese
Animal ExperimentationAnimal Experimentation Introduction Animal experimentation has been a part of biomedical and behavioral research for several millennia; experiments with animals were conducted in Greece over 2,000 years ago. Many advances in medicine and in the understanding of how organisms function have been the direct result of animal experimentation. Concern over the welfare of laboratory animals is also not new, as reflected in the activities of various animal welfare and antivivisectionist groups dating ba
FluorideFluoride Fluoride is a mineral that occurs naturally in almost all foods and water supplies. The fluoride ion comes from the element fluorine. Fluorine, the 13th most abundant element in the earth\'s crust, is never encountered in its free state in nature. It exists only in combination with other elements as a fluoride compound. Fluoride is effective in preventing and reversing the early signs of tooth decay. Researchers have shown that there are several ways through which fluoride achieves its
