21. Thus, the two products are berberine, nicotinamide adenine dinucleotide phosphate, and hydrogen ion. 22. The systematic name of this enzyme class is "'nicotinamide amidohydrolase " '. 23. See for example the entry to Nicotinamide adenine dinucleotide ( an old nutshell of mine ). 24. In 2004, Charles Brenner and co-workers uncovered the nicotinamide riboside kinase pathway to NAD. 25. Cationic Acetylcholine binding to a tryptophan residue of the nicotinamide acetylcholine receptor via a cation ? effect. 26. Niacin and nicotinamide bind to the receptor " in vitro " with very low affinity. 27. The 3 products are L-alanine, pyruvate, nicotinamide adenine dinucleotide, and hydrogen ion. 28. The 3 products are beta-alanine, pyruvate, nicotinamide adenine dinucleotide, and hydrogen ion. 29. The pill contains a chemical similar to nicotinamide adenine dinucleotide ( NAD ) used in metabolic reactions. 30. Thus, the two products are 1-( beta-D-ribofuranosyl ) nicotinamide and hydroquinone.
