Name : Nicotinamide Adenine Dinucleotide
Shape : White crystalline powder
1. It is an essential coenzyme in organisms, used in biochemical research, clinical diagnosis, clinical drugs and drug research.
2. Nicotinamide adenine dinucleotide is a coenzyme drug. Clinically, it is mainly used for the auxiliary treatment of coronary heart disease, which can improve chest tightness, angina and other symptoms. Adverse reactions occasionally see dry mouth, dizziness, nausea and so on.
3. Participate in energy and material metabolism in the body, which is conducive to cell repair and renewal. It is used for the treatment of coronary heart disease, myocarditis, leukopenia and other diseases.
Nicotinamide adenine dinucleotide (NAD), In mammals, there are two states: oxidized form (NAD+) and reduced form (NADH). Oxidized form (NAD+) has the maximum UV absorption spectrum at 260nm and becomes reduced form (NADHChemicalbook) by accepting a hydrogen atom and an electron from the substrate through various deaminase. There is a maximum absorption at 340nm. β-nicotinamide adenine dinucleotide is used as a coenzyme in REDOX reactions, as a donor for the ADP-ribose moiety in ADP-ribosylation reactions, and as a precursor for the second messenger molecule cyclic ADP-ribose. β-nicotinamide adenine dinucleotide 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.
