Division of unsaturated fatty acid

Unsaturated fatty acid containing one double bond

Unsaturated fatty acid containing two or more double bond

Derived from 20 carbon of polyenoic fatty acid comprising the prostanoids, leukotrienes and lipoxins

It acts as local hormone and synthesized from eicosanoic polyunsaturated fatty acid to form cyclopentane ring

A cyclopentane ring interrupted with an oxygen atom

It signifies "9 position keto" in prostaglandin

it signifies "9 position hydroxyl"

Other name of phosphatidylethanolamine

Important constituent f the cell membrane phospholipids which serves as precursor of second messenger

2 second messenger produced by Phosphatidylinositol 4,5 biphosphate

Major lipid of mitochondrial membrane

These are the intermediates in the metabolism of phosphoglycerol

These are important in the metabolism and interconversions of phospholipids

Found in oxidized lipoprotein and can promote atherosclerosis

This is the 10% of the phospholipid of the brain
