Nicotinamide CAS 98-92-0

Nicotinamide, also known as nicotinamide, vitamin B3, or vitamin PP, is a water-soluble vitamin belonging to the B vitamins. It is a component of coenzyme I (nicotinamide adenine dinucleotide, NAD) and coenzyme II (nicotinamide adenine dinucleotide phosphate, NADP). In the human body, the nicotinamide portion of these two coenzymes exhibits reversible hydrogenation and dehydrogenation properties, playing a hydrogen transfer role in biological oxidation. It promotes tissue respiration, biological oxidation processes, and metabolism, and is crucial for maintaining the integrity of normal tissues, especially the skin, digestive tract, and nervous system. Deficiency can lead to pellagra due to impaired cellular respiration and metabolism; therefore, this product is mainly used to prevent and treat pellagra, stomatitis, and glossitis.
