Concept explainers
(a)
Interpretation:
The intermediate generated in the first cycle of the lipogenesis pathway that has a carbon chain that is derived from a C4 keto monoacid has to be identified.
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 cyclic process occurs in the enzyme fatty acid synthase. The one turn of this cyclic process constitutes four reactions. The various intermediates formed in the process are associated with a carrier protein known as ACP.
Keto monoacid is the compound that has a keto group and
(b)
Interpretation:
The intermediate generated in the first cycle of the lipogenesis pathway that has a carbon chain that is derived from a C4 unsaturated monoacid has to be identified.

Interpretation:
The intermediate generated in the first cycle of the lipogenesis pathway that has a carbon chain that is produced by a dehydration reaction has to be identified.
