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. [...]
In this article we will discuss about the metabolism of sphingolipids, explained with the help of a suitable diagram. Sphingosine results from the condensation of palmityl-coenzyme A with serine. The next step consists in the binding of a fatty acid which gives a ceramide. This ceramide can react either with CDP-choline to form a sphingomyelin, or with UDP-galactose to give [...]
In this article we will discuss about the process of metabolism in amino acids. We know that ammonia can be formed and then be found in the form of amino group of glutamic acid. We have studied the reactions — transamination and deamination — by which amino groups can be added to or removed from amino acids. The forms in [...]
