Niacin is also involved in the synthesis of protein, fat, and pentoses needed for nucleic acid formation. Niacin is a major constituent of the coenzyme nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP).These compounds function to remove hydrogen atoms during biological reactions.iacin is also involved in the synthesis of protein, fat, and pentoses needed for nucleic acid formation. Niacin is a major constituent of the coenzyme nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP).
The nicotinamide coenzymes are nicotinamide adenine dinucleotide (NAD +) and nicotinamide adenine dinucleotide phosphate (NADP +). Both are derived from the vitamin niacin (nicotinic acid) (Fig. 7.7), the deficiency of which causes the disease pellagra. Niacin is present in many cereals, meat, and legumes.e will use this chapter to introduce all of the vitamins and coenzymes. In a few cases--NAD + , FAD, coenzyme A--the mechanisms of action will be covered. For the remainder of the water-soluble vitamins, discussion of function will be delayed until we encounter them in metabolism.
