Biology  Lipase  Lipid bilayer

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, ...

Any organic molecule that is insoluble in water but is soluble in nonpolar organic solvents. Lipids contain covalently linked fatty acids and are found in fat droplets and, as phospholipids, in biomembranes.

Lipids are uniquely biological molecules, and they are synthesized and used by organisms in a variety of important ways.

A fatty or waxy organic compound that is readily soluble in nonpolar solvent (e.g. ether) but not in polar solvent (e.g water).

Fats and lipids are one of the four basic kinds of organic molecules. Unlike the other three however, rather than sharing a common Chemistry and structure, ...

Lipid binding to channels
How are the effects of anionic lipid on channel function to be understood? In some cases the interaction of lipid with a membrane protein is highly specific.

LIPIDAT: The Lipid Thermodynamic Database Project was initiated to collect in one, central depository all information on lipid mesomorphic and polymorphic transitions and miscibility.

Biological Molecules and Enzymes
Lipids are made up of the elements carbon, hydrogen and oxygen but in different proportions to carbohydrates. The most common type of lipid is the triglyceride.

Lipids are a structurally heterogeneous group of compounds characterized by the presence of distinct hydrophilic and hydrophobic domains.

Lipid Bilayer Structure
The lipid bilayer is a universal component of all cell membranes. Its role is critical because its structural components provide the barrier that marks the boundaries of a cell.

Lipids can be used for energy storage in the form of fat in humans and oil in plants.
Lipids can be used as heat insulation as fat under the skin reduces heat loss.

A membrane-anchored phospholipid that transduces hormonal signals by stimulating the release of any of several chemical messengers.

Lipids of cell membranes include phospholipids composed of glycerol, fatty acids, phosphate, and a hydrophobic organic derivative such as choline or phosphoinositol.

Lipids are the masters of energy storage, and some have important structural roles or serve as hormones, among other things.

lipids One of the four classes of organic macromolecules. Lipids function in the long-term storage of biochemical energy, insulation, structure and control. Examples of lipids include the fats, waxes, oils and steroids (e.g.

Lipid and Polysaccharide Antigens
Lipid Antigens
Lipid antigens are presented to T cells by cell-surface molecules designated CD1 ("cluster of differentiation" 1).

Lipid-soluble hormones have intracellular receptors.
Evidence for intracellular receptors for steroid hormones came in the 1960s.

Lipids are technically not polymers, they are either a combination of glycerol and fatty acids or a steroid
Lipids are used in energy storage, membrane structure, insulation ...

lipids /LIP-ədz/ Any of a wide variety of biological molecules, which are only sparingly soluble in water, including fats, fat-soluble vitamins, monoglycerides, diglycerides, phospholipids, waxes and sterols.

Lipids are compounds that are insoluble in water but soluble in nonpolar solvents.
Some lipids function in long-term energy storage. One gram of fat stores more than twice as much energy as one gram of carbohydrate.

Lipids: Fats and Sterols
Important facts about Fats in your diet:
Unsaturated (mono, poly trans, omega), Saturated, Essential.

lipid an organic molecule used to form cellular and organelle membranes, the sheaths surrounding nerve fibers, and certain hormones; includes fats as an energy source.

Lipids are involved mainly with long-term energy storage. They are generally insoluble in polar substances such as water.

Phospholipid. A class of lipid molecules in which a phos- phate group is linked to glycerol and two fatty acyl groups. A chief component of biological membranes. (See Inositol phospholipid.) ...

lipid A fat, oil, or fatlike compound that usually has fatty acids in its molecular structure. An organic compound consisting mainly of carbon and hydrogen atoms linked by nonpolar covalent bonds.

The lipid binding properties of apolipoprotein (apo) AIMilano, a molecular variant of human apolipoprotein AI, characterized by the Arg173----Cys substitution, was investigated by the use of dimyristoylphosphatidylcholine liposomes.
