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 solid bonds, while oleic acid is an
unsaturated fatty acid has one solid bond (also described as olefinic) and
polyunsaturated fatty acids like linolenic acid contain two or more solid
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. |
