Interpretation Introduction

Interpretation:

The correct characterization for the first step in the first turn of the chain elongation phase of lipogenesis 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.

There is a cyclic process for the chain elongation that 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.
