(a)
Interpretation:
The number of turns of the fatty acid biosynthetic pathway needed for the biosynthesis of a C14 saturated fatty acid from acetyl CoA molecules has to be determined.
Concept introduction:
Lipogenesis is the process employed for the synthesis of fatty acid. The starting precursor for the synthesis is acetyl CoA. The enzyme employed for the process is fatty acid synthase. It is a multienzyme complex that ties the reaction responsible for the synthesis of fatty acid. The fatty acid is synthesized in two parts. In the first part, there is citrate-malate shuttle system and in the second part, there is a cyclic process to synthesize saturated fatty acid.
The different reactions that are involved in the cyclic process are:
(b)
Interpretation:
The molecules of malonyl ACP that must be formed in the biosynthesis of a C14 saturated fatty acid from acetyl CoA molecules has to be determined.
