In this article we will discuss about:- 1. Nature of the Carbohydrate Part 2. Nature of the Glycan-Protein Linkage 3. Biosynthesis of Glycoproteins 4. Importance of Glycoproteins 5. Role of Glycan Groups. Nature of the Carbohydrate Part: 1. Monosaccharide Constituents of Glycans: The monosaccharides constituting the glycans belong to the 4 categories described above. The most common are: 1. Neutral [...]
In this article we will discuss about the process of metabolism of glycerolipids, explained with the help of suitable diagrams. Synthesis and Degradation of Glycerophospholipids: The common precursor of all phosphatides is phosphatidic acid. There are two pathways for carrying out the biosynthesis of this lipid. In the first, glyceraldehyde-3-phosphate, which is one of the intermediates of glycolysis (see fig. [...]
In this article we will discuss about the classification of lipids. Contrary to carbohydrates which constitute a family of relatively homogenous compounds, lipids form a very heterogenous class of compounds of widely differing structures and grouped according to their insolubility in water and solubility in organic solvents (ether, acetone, chloroform-alcohol mixtures, etc.). These solubility criteria are not absolute. Lipids were [...]
