Classification of lipids
1) Simple lipids
i) Triacylglycerol-TAG –neutral fat
ii) Waxes
2) Compound lipids
i) Phospholipids
(a) N containing glycerophosphatides
1. Lecithin-Phosphatidyl choline
2. Cephalin- Phosphatidyl ethanolamine
3. Phosphatidyl serine
(b) Non-N containing glycerophosphatides
1. Phosphatidyl inositol
2. Phosphatidyl glycerol
3. Diphosphatidyl inositol- Cardiolipin
(c) Plasmalogens containing Long Chain Alcohols
1. Choline plasmalogens
2. Ethanolamine plasmalogens
(d) Phospho sphingosides containing sphingosine
1. Sphingomyelin-brain & nerve tissue(neuron)
ii) Non-phosphorylated lipids
(a) Glycosphingolipids(Glycolipids)-Fatty acids, sphingosine, carbohydrates
1. Cerebrosides-Ceremide monohexosides
2. Gangliosides-having N-acetyl neuraminic acid
(b) Sulpholipids
1. Sulphated Cerebrosides
2. Sulphated Gangliosides
iii) Derived lipids-Fatty acids, steroids, prostaglandins
iv) Lipids complexed to other compounds- Lipoproteins
