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 family of compounds that cannot be dissolved or mixed in water Examples of lipids include fats, phospholipids, and steroids
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
Any of a group of fats and fat-like compounds, including sterols, fatty acids and many other substances
