For humans, the efficiency of conversion is estimated as requiring 60 mg of tryptophan to make 1 mg of niacin. Riboflavin, vitamin B 6 and iron are required for the process. [20] Pellagra is a consequence of a corn-dominant diet because the niacin in corn is poorly bioavailable and corn proteins are low in tryptophan compared to wheat and rice ...
Some NAD is converted into the coenzyme nicotinamide adenine dinucleotide phosphate (NADP), whose chemistry largely parallels that of NAD, though its predominant role is as a coenzyme in anabolic metabolism. In the name NAD +, the superscripted plus sign indicates the positive formal charge on one of its nitrogen atoms. A biological coenzyme ...
Niacin: Niacin is composed of two structures: nicotinic acid and nicotinamide. There are two co-enzyme forms of niacin: nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Both play an important role in energy transfer reactions in the metabolism of glucose, fat and alcohol. [13]
