GENERAL DESCRIPTION OF FATTY ACID
Fatty Acids are aliphatic carboxylic acid with varying hydrocarbon lengths at one end of the chain joined to terminal carboxyl (-COOH) group at the other end. The general formula is R-(CH2)n-COOH. Fatty acids are predominantly unbranched and those with even numbers of carbon atoms between 12 and 22 carbons long react with glycerol to form lipids (fat-soluble components of living cells) in plants, animals, and microorganisms. Fatty acids all have common names respectively lilk lauric (C12), MyrIstic (C14), palmitic (C16), stearic (C18), oleic (C18, unsaturated), and linoleic (C18, polyunsaturated) acids. The saturated fatty acids have no double bonds, while oleic acid is an unsaturated fatty acid has one double bond (also described as olefinic) and polyunsaturated fatty acids like linolenic acid contain two or more double bonds. Lauric acid (also called Dodecanoic acid) is the main acid in coconut oil (45 - 50 percent) and palm kernel oil (45 - 55 percent). Nutmeg butter is rich in myristic acid (also called Tetradecanoic acid ) which constitutes 60-75 percent of the fatty-acid content. Palmitic acid(also called Hexadecylic acid ) constitutes between 20 and 30 percent of most animal fats and is also an important constituent of most vegetable fats (35 - 45 percent of palm oil). Stearic acid ( also called Octadecanoic Acid)  is nature's most common long-chain fatty acids, derived from animal and vegetable fats. It is widely used as a lubricant and as an additive in industrial preparations. It is used in the manufacture of metallic stearates, pharmaceuticals, soaps, cosmetics, and food packaging. It is also used as a softener, accelerator activator and dispersing agent in rubbers. Oleic acid (systematic chemical name is cis-octadec-9-enoic acid) is the most abundant of the unsaturated fatty acids in nature.

APPLICATIONS
Saturated fatty acids are predominantly in animal fats and tropical oils and can be produced by hydrogenation of unsaturated fatty acids. Arachidic acid, a saturated 20-carbon fatty acid, is found in fish oils and vegetable oils such as peanut. Saturated fatty acids increase serum low-density lipoproteins resulting in high blood cholesterol levels. Arachidic Acid is used as a lubricant and as an emulsifier in industrial preparations. It is used in the manufacture of pharmaceuticals, soaps, cosmetics, and food packaging. It is used as a softener and dispersing agent. It is used in making quaternary ammonium products for detergents and biocides.
