Nicotinamide adenine dinucleotide (NAD) is a cofactor found in all living cells. The compound is called a dinucleotide because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine nucleobase and the other nicotinamide. Nicotinamide adenine dinucleotide exists in two forms: an oxidized and reduced form, abbreviated as NAD+ and NADH respectively.
1.Nicotinamide Adenine Dinucleotide is a water-soluble vitamin, The product is white crystalline powder, odorless or nearly odorless, bitter in taste, freely soluble in water or ethanol, dissolvable in glycerin.
2.Nicotinamide Adenine Dinucleotide is easy to absorb oral, and can be widely distributed in the body, the excess metabolites or prototype quickly expel from urine. Nicotinamide is part of coenzyme I and coenzyme II, plays the role of hydrogen delivery in biological oxidation respiratory chain, can promote biological oxidation processes and tissue metabolism, maintain normal tissue (especially the skin, digestive tract and nervous system) integrity has an important role.
3.Nicotinamide Adenine Dinucleotide has prevention and treatment of heart block, sinus node function and anti fast experimental arrhythmias, nicotinamide can significantly improve the heart rate and atrioventricular block caused by verapamil.
β-Nicotinamide Adenine Dinucleotide is a coeznyme consisting of an adenine base and a nicotinamide base connected by a pair of bridging phosphate group. β-Nicotinamide Adenine Dinucleotide acts as a c oenzyme in redox reactions, as a donor of ADP-ribose moieties in ADP-ribosylation reactions and also as a precursor of the second messenger molecule cyclic ADP-ribose. β-Nicotinamide Adenine Dinucleot ide also acts as a substrate for bacterial DNA ligases and a group of enzymes called sirtuins that use NAD+ to remove acetyl groups from proteins.
