MSH: A water-soluble vitamin of the B complex occurring in various animal and plant tissues. It is required by the body for the formation of coenzymes NAD and NADP. It has PELLAGRA-curative, vasodilating, and antilipemic properties.,CSP: nicotinic acid (3-pyridinecarboxylic acid) and its derivatives; a water soluble B vitamin which is the precursor of NAD and NADP.,NCI: Water-soluble vitamin that is a cosubstrate or coenzyme with numerous dehydrogenases for the transfer of the hydride ion. (DRI),PDQ: A water-soluble vitamin belonging to the vitamin B family, which occurs in many animal and plant tissues, with antihyperlipidemic activity. Niacin is converted to its active form niacinamide, which is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and its phosphate form, NADP. These coenzymes play an important role in tissue respiration and in glycogen, lipid, amino acid, protein, and purine metabolism. Although the exact mechanism of action by which niacin lowers cholesterol is not fully un
