Explain about the Niacin - Water Soluble Vitamin?
Niacin is chemically synonymous with nicotinic acid although the term is also used for its amide (nicotinamide). Nicotinamide is required for the synthesis of the active forms of niacin i.e. nicotinamide adenine dinucleotide (NAD) and its phosphate nicotinamide adenine dinucleotide phosphate (NADP), which functions as a cofactor for various coenzymes in our body. Nicotinic acid was first isolated from rice polishing and shown to be a component of coenzyme I and II and several transporting enzymes in the tissues.
