Defination / Uses

Fatty acids are a kind of fatty acid. Long chains of lipid-carboxylic acid that are contained in fats and oils, as well as in cell membranes as phospholipids and glycolipids. (A carboxylic acid is an organic acid with the -COOH functional group.)

Animal and vegetable fats and oils include fatty acids. Fatty acids are used as lubricants, in cooking and food engineering, and in the manufacturing of soaps, detergents and cosmetics outside of the body.

In plants, animals, and microorganisms, fatty acids are an important component of lipids (fat-soluble components of living cells).Our fatty acid calculator allow you to calculate fatty acids of samples. A fatty acid, in general, is made up of a straight chain with an even number of carbon atoms, hydrogen atoms running the length of the chain and at one end, and a carboxyl group (COOH) at the other end. It's because of the carboxyl group that it's an acid. The acid is saturated if all of the carbon-to-carbon bonds are single; if any of the bonds are double or triple, the acid is unsaturated and more reactive. Fatty acids are not found in nature in a free state; instead, they are commonly found in the form of triglyceride, which is a combination of fatty acids and glycerol (an alcohol).
