Concept explainers
Interpretation:
The total number of different B vitamins that participates in the reactions involved in lipid
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
