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 [...]
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 [...]
The biosynthesis of the DNA must consist in a replication or duplication. The study of the DNA structure as proposed by Crick and Watson (see fig. 6-15) gives an idea of the mechanism of this replication. Each nucleotide of the template DNA chain need only be recognized by a complementary nucleotide before the latter is incorporated at the end of [...]
