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 [...]
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. [...]
