The Different Kinds of Phospholipids by Denise McKee, Ph.D. There are five general classes of phospholipids. These are phosphatidylserine. Phospholipids. Phospholipids are esters of glycerol, fatty acids, phosphoric acid, and other alcohols. The most common phospholipids are phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylserine.

Characterization[ edit ] Phospholipids are optically highly birefringenti.

TYPES OF PHOSPHOLIPIDS PDF DOWNLOAD

Measurement of birefringence can be achieved using cross polarisers in a microscope to obtain an image of e. Galactolipid and Sulpholipid These lipid are found in chloroplast.

One or two types of phospholipids residue are connected by glycosidic linkage at Carbon-3 of a diacylglycerol.

Galactolipid are present in the thylakoid inner membrane of the chloroplast. They are most abundant membrane lipid. Sulphonoted glucose residue is joined to a diacylyglycerol by glycosidic linkage.

Sulphonate hard group bears a fixed negative charge. Sphingolipid Sphingolipids, which is 4th large class of membrane lipid.

Sphingomyelins are found in the brain and nervous tissue in large quantity.

Sphinogolipid consist of one molecule of long chain amino alcohol Sphingosine are also called as 4-sphingenine, phosphoric acid, choline and fatty acid. Glycerol is absent in sphingolipid.

The fatty acid which is attached to the NH2 group of carbon-2 by amide linkage this is known as ceramide.

All sphingolipids are derivative of ceramide e. Sphingomyelin have phosphocholine or phosphoethanol amine at their head group. Sphingomyelins are present in plasma membrane of the animal cell.

Prominently present in myelin a membraneous sheath which is surround the exon of neurons called as sphingomyelin. It is present largely on the outer surface of plasma membrane. One or more sugar types of phospholipids directly to the carbon-1 of OH of the ceramide. In this lipid phosphate is absent.

Cerebrosides and globosides called neutral glycolipid because at pH-7, neutral net charge is zero. Gangliosides is a sphingolipid and it contain oligosaccharides at their polar head group.

But choline itself is not synthesized by the cell. For this, the dietary source is utilized and choline is synthesized. This choline when taken up by the cell is quickly phosphorylated by choline kinase and hence phosphocholine is types of phospholipids.

types of phospholipids Then the product obtained reacts with cytidine triphosphate forming cytidine diphosphocholine. Then in the endoplasmic reticulum is CDP- choline, that catalyses reaction of cytidine diphosphocholine with sn- 1,2 diacylglycerols forming phosphatidylcholine.

The reaction here is types of phospholipids explained in some simple steps but the complete process is much more elaborated. The third hydroxyl group of glycerol attached with a phosphoric acid through a phosphate ester bond.
