Monosaccharides, and particularly glucose, owe their importance to the fact that their oxidation provides the living organisms with a major part of the energy they require. Furthermore, the carbon atoms of glucose can be found in a large number of compounds (amino acids, fatty acids, sterols, glycerol, etc.). In the study of the metabolism of carbohydrates we will therefore come [...]
In this article we will discuss about the interrelations between carbohydrates and lipid metabolisms. Transformation of Carbohydrates into Lipids: In most animals and in man, when dietary carbohydrates are in excess, the oxidation of a part of glucose maintains relatively high concentrations of ATP, NADH and NADPH; this will promote: i. The synthesis of glycogen from glucose, which requires UTP [...]
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 [...]
