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 digestion and absorption of lipids. Digestion of Lipids: Whereas previous hydrolyzing action of enzymes is the determining factor for the absorption of carbohydrates and proteins, absorption of lipids depends not only on the presence of lipolytic enzymes, but also on the degree of emul-sification of lipids in the intestine. In [...]
The below mentioned article provides a note on the process of ketogeneis, explained with the help of a suitable diagram. In vertebrates, the acetyl-coenzyme A originating from the β-oxidation can leave the mitochondrion in the form of citrate. However a notable part of this acetyl-coA is used for the synthesis of ketone substances: acetoacetic acid, β-hydroxy-butyric acid and acetone. This [...]
