In this article we will discuss about:- 1. Isomerism of Monosaccharides 2. Cyclic Structure of Monosaccharides 3. Types 4. Compounds Derived 5. Nomenclature 6. Chemical Properties. The monosaccharides or simple sugars are molecules containing several alcohol groups as well as a reducing group, either aldehyde or ketone. Monosaccharides are classified according to the number of carbon atoms of their molecules [...]
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 the process of biosynthesis of steroids, explained with the help of suitable diagrams. Biosynthesis of Cholesterol: The main steps of the biosynthesis of cholesterol are diagrammatically represented in figure 5-22. The first reaction consists of the condensation of 2 molecules of acetyl-coA. It is the reverse of the reaction which takes place during [...]
