Whether the B-vitamin niacin is involved in (1) β-oxidation pathway, (2) ketogenesis, (3) lipogenesis, or (4) conversion of ketone bodies to acetyl CoA has to be determined. Concept introduction: Niacin includes NAD + , NADH and NADPH coenzymes. Niacin and nicotinamide are precursors of the coenzyme NAD and NADP. Both NAD and NADP are involved in many dehydrogenation reactions. While NAD participates in the catabolic activities, NADP participates in the anabolic activities.
