Lipids are a group of organic compounds characterized by their presence in plants and animals, and their insolubility in water. They are extracted from cells using solvents such as ether or benzene that are non-polar. They are composed of mainly...

The lipids are one of four major families of biochemical compounds, the other three being carbohydrates, proteins, and nucleic acids. Biochemical compounds are organic (carbon-containing) compounds that occur in living organisms. The lipids are unique...

Lipids belong to a broad class of animal- and plant-derived compounds which include fats and oils. They are insoluble in water because they are composed primarily of long chains of hydrocarbons. Some lipids, such as fats, are solid or semisolid at room...

A lipid is a molecule that is at least partially composed of a chain of hydrocarbons--carbons in association with hydrogen molecules. Hydrocarbon chains tend to exclude water, because there are no vacant sites along the chain for the water to bind to,...

Lipids are a group of compounds that are rich in carbon-hydrogen bonds and are generally insoluble in water. The main categories are glycerolipids, sterols, and waxes. Glycerolipids have fatty acids attached to one or more of the three carbons of...

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...

Lipids are molecules that have the properties of FAT. Neuronal membranes are composed of lipids known as PHOSPHOLIPIDS (because they contain phosphates). Other lipids in neural tissue are the CEREBROSIDES, found in MYELIN. Cerebrosides are members of...

One of the substances that comprise the four major classes of compounds that constitute the living body (the others are CARBOHYDRATES, NUCLEIC ACIDS and PROTEINS). They include FAT, STEROIDS, terpenes and waxes. Lipids contain fatty acids and are...

A class of molecules which are mostly straight chain. The chain length is between 12 and 24 carbon atoms. Biological membranes contain roughly 50% lipids and 50%...

Lipids are broadly defined as any fat-soluble (lipophilic), naturally-occurring molecules, such as fats, oils, waxes, cholesterol, steroids, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and...
