Nicotinamide nucleotides

These coenzymes are derived from  the vitamin, niacin. They are of two  types, nicotinamide  adenine dinucleotide (NAD')  and nicotinamide adenine dinucleotide phosphate (NADP').  Collectively,  they are called as pyr~dine  nucleotides. In NAD',  the pyridine ring  is attached to a ribose molecule through glycosidic bond and the phosphate provides a link  between adenosine and nicotinamide riboside.  In  NADP',  an  aqditional phosphate group  is present  in  carbon  atom  2 of  the ribose molecule  of adenosine component.
