Oily substances that include things like fats, oils and waxes Sebum is made up of lipids A particular kind of lipid, free fatty acids, are irritating to the skin
Diverse class compounds, including fats, oils, fatty acids, triglycerides and steroids essential for membrane formation, energy stores and fuel molecules
Another name for fats People with kidney failure tend to have raised lipid levels in the blood
Group of fatty substances that are stored in the body and can be measured in the blood; they include high-density lipoproteins (HDL; "good cholesterol"), low-density lipoproteins (LDL; "bad cholesterol"), and triglycerides, among other compounds
Lipids are also known as fats, but they include compounds of many different kinds Chemically, these compounds are built on a backbone of glycerol, which was a three-carbon chain Each carbon, in turn, bonds via an oxygen molecule to so-called fatty acids Fatty acids have an acid group (COOH) at one end that is attached to a chain of carbons Lipids differ mainly in the nature of the fatty acid chains
liquid fats; fats or fat-like substances, characterized by their insolubility in water and solubility in fat solvents such as alcohol, ether or chloroform A descriptive rather than chemical term Includes "true" fats (esters of fatty acids and glycerol); lipoids (phospholipids, cerebrosides, waxes); and sterols (cholesterol, ergosterol)
oily substances that include, fats, oils and waxes Sebum, the oily secretion from sebaceous glands, is made up of lipids
Any of a special group of fat and fat like substances typically water-insoluble Serving as sources of fuel, they are easily stored in the body, and some are important constituents of cell structure, namely linoleic acid (omega 6) and alpha-linoleic acid (omega 3) Referred to as essential fatty acids, the body cannot make these two and rely's exclusively on dietary sources Most omega 3 and 6 available in the diet is extensively damaged from light and or oxygen exposure before being consumed Almost without exception, most vegetable oils on the market have been extensively processed using solvents and high levels of heat to standardize their odor, taste and extend their shelf life, rendering the oil totally denatured and a major cause of Arteriosclerosis and heart disease
Any of a group of organic compounds including the fats, oils, waxes, sterols, and triglycerides. Lipids are characterized by being insoluble in water, and account for most of the fat present in the human body. They are, however, soluble in nonpolar organic solvents
an oily organic compound insoluble in water but soluble in organic solvents; essential structural component of living cells (along with proteins and carbohydrates)
Descriptive term for a fat or fat-like substance found in the blood, such as cholesterol The body stores fat as energy for future use just like a car that has a reserve fuel tank When the body needs energy, it can break down the lipids into fatty acids and burn them like glucose (sugar)
A lipid is one of a group of naturally occurring compounds, also known as fat, that are soluble in organic solvents such as chloroform or alcohol, but insoluble in water Lipids are important dietary constituents, not only because of their high energy value, but also because certain vitamins and essential fatty acids are associated with them
Any of a group of organic compounds including the fats, oils, waxes, sterols, nucleic acids, and triglycerides. Lipids are characterized by being insoluble in water, and account for most of the fat present in the human body. They are, however, soluble in nonpolar organic solvents
one of several types of fatty substances in living things, such as fat, oil, or wax (lipide, from lipos ). Any of a diverse class of organic compounds, found in all living things, that are greasy and insoluble in water. One of the three large classes of substances in foods and living cells, lipids contain more than twice as much energy (calories) per unit of weight as the other two (proteins and carbohydrates). They include the fats and edible oils (e.g., butter, olive oil, corn oil), which are primarily triglycerides; phospholipids (e.g., lecithin), which are important in cell structure and metabolism; waxes of animal or plant origin; and sphingolipids, complex substances found in various tissues of the brain and nervous system. Since insolubility is the defining characteristic, cholesterol and related steroids, carotenoids (see carotene), prostaglandins, and various other compounds are also classifiable as lipids
A lipid is a water insoluble (hydrophobic) substance and is the name of a large class of structurally and functionally diverse molecules Important lipids include fatty acids (saturated and unsaturated), they are a component of phospholipids and fats - phospholipids, main component of biological membranes composed of glycerol phosphate backbone, fatty acid substituents, and hydrophobic headgroups - sterols, cholesterol derived membrane components, (sex) hormones, and bile salts (intestinal detergents)
Is an organic compound composed of carbon atoms that have two hydrogen atoms attached Lipids are commonly known as fats and oils, and belong to the family of molecules known as hydrocarbons
A class of hydrophobic molecules consisting mainly of fats, oils and waxes that generally possess long non-polar hydrocarbon groups arranged in chains (commonly termed fatty acid chains) One type, the phospholipids, is a major component of plant and animal membranes
A term for fat The body stores fat as energy for future use just like a car that has a reserve fuel tank When the body needs energy, it can break down the lipids into fatty acids and burn them like glucose (sugar)
Lipids are soluble in non- aqueous solvents such as white spirit or dry cleaning fluid Lipids tend to associate with one another, just as oil forms droplets in water Many lipids have head groups which like water but leg groups which are oily (see Fig 3 4) Different head groups define several classes of lipid The leg groups, are much the same for each class, a mixture of hydrocarbon chains Lipids can form back to back sheets in water, forming the basis for membranes
