fatty acids

fatty acids
lipid lip"id n. [Gr. li`pos fat.] (Chem., Biochem.) Any of a variety of oily or greasy organic compounds found as major structural components of living cells; they are insoluble in water but soluble in organic solvents such as alcohol and ether, and include the common {fats}, {cholesterol} and other steroids, {phospholipids}, {sphingolipids}, {waxes}, and {fatty acids}; some of the lipids, together with proteins and carbohydrates, form an essential structural component of living cells, as in the cell walls and membranes. The term lipid refers to its solubility in nonpolar solvents, and has no significance with regard to chemical structure.

Syn: lipide, lipoid. [WordNet 1.5]
