β-NADH, a pyridine nucleotide and biologically active form of nicotinic acid, is a coenzyme necessary for the catalytic reaction of certain enzymes. β-NAD+ is a carrier for hydride ion, forming β-NADH. The hydride ion is enzymatically removed from a substrate molecule by the action…

β-NADP is a coenzyme necessary for the alcoholic fermentation of glucose and the oxidative dehydrogenation of other substances. It occurs widely in living tissue, especially in the liver. Nicotinic acid can be converted to nicotinamide in the body and, in this form, is found as a component of…

Adenosine 5′-diphosphate is a P2Y receptor agonist. Adenosine 5′-diphosphate has been used to study the release, neuronal effects and removal of extracellular β-nicotinamide adenine dinucleotide (β-NAD+) in the rat brain. Adenosine 5′-diphosphate has also been used to…

β-NAD is one of the biologically active forms of nicotinic acid. Occurs in living cells, primarily in the oxidized state Coenzyme for dehydrogenases NAD usually acts as a hydrogen acceptor, forming NADH Major electron acceptor molecule in biological oxidations. Acts as a…

Adenosine is a nucleotide resulting from the union of one molecule of sugar -- d-ribose -- with a base -- l-adenine. Active in cardiovascular disorders Indicated in cases of angina pectoris Increases coronary output Vasodilator action Induced apoptosis in human leukemia HL-60…

Guanosine-5'-triphosphate, a purine nucleotide, is required as a coenzyme for protein biosynthesis in a cell-free system. Substrate for RNA polymerases Substrate for wide range of GTPases GTP functions as a carrier of phosphates and pyrophosphates involved in channeling chemical…
