In this article we will discuss about the process of biosynthesis of fatty acids, explained with the help of suitable diagrams. Synthesis of Saturated Fatty Acids: It must be pointed out at the very outset that the biosynthesis of fatty acids does not generally take place by the reactions — in the reverse direction — of β-oxidation; the latter are [...]
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 [...]
