Short notes on compound and deride lipids

Compound Lipids

Compound Lipids contain other radicals in addition to the three fatty acid radicals combined with one molecule of glycerol.

ADVERTISEMENTS:

Phospholipids are those triglycerides which have phosphate radicals in them. Two examples are lecithin and cephalin. The body contains a large numbers of phospholipids. They are generally found in tissue and blood. The tissue of the nervous system and liver are exceptionally rich in phospholipids. Phospholipids help in emulsifying fats which makes their digestion much easier.

The cerebrosides presents in the brain are triglycerides which contain a carbohydrate molecule in them, in addition to the fatty acid radicals and glycerol. Lipoproteins are compound lipids containing a protein molecule in the triglyceride.

Deride lipids.

This group includes fatty acid alcohol carotenoids and fat-soluble vitamins like vitamins A, D, E, and K.

ADVERTISEMENTS:

The total number of fatty acids found in the nature exceeds forty. Like most complex organic substances, fatty acids contain large number of carbon atom and these exist in small groups along with hydrogen and oxygen atoms. Sometimes other atoms may be present. These groups are joined together in chain like structures. Fatty acids may be short-chain acid which contain only up to 6 atoms of carbon. Medium chain fatty acid contain up to 12 carbon atoms and long chain acid contain more than 12 carbon atoms. The number of carbon atoms in a fatty acid is generally even.
