Interpretation Introduction

Interpretation:

The total number of different B vitamins that participates in the reactions involved in lipid metabolism has to be determined.

Concept introduction:

The biological process of lipid metabolism includes β-oxidation, ketogenesis, and lipogenesis. β-oxidation is the breakdown of lipid molecule chains into acetyl CoA and a molecule of acyl CoA whose length is smaller than the length of the reactant molecule. Ketogenesis involves the formation of ketone bodies by a series of four reaction steps, where molecules of acetyl CoA act as initial reactants. The lipogenesis process is the reverse of ketogenesis. In this process, fatty acid molecules are produced from the acetyl CoA molecules.
