On a structure nicotinic acid is close to a nikotinamid.
Nicotinic acid and nikotinamid contain in bodies of animals (a liver, kidneys, muscles, etc.), in milk, fish, yeast, vegetables, fruit, buckwheat and other products. Nicotinic acid and its amide play an essential role in activity of an organism: they are prostetichesky groups of enzymes - kodegidraza of I (a diphosphopyridinnucleotide - OVER) and the kodegidraza of II (a trifosfopiridinnukleotid - NADF) which are carriers of hydrogen and carrying out oxidation-reduction processes. Kodegidraza II participates also in phosphate transfer. Insufficiency of RR vitamin at the person leads to development of a pellagra (the illness caused by insufficiency of the RR nicotinic acid / vitamin/, tryptophane and B2 Riboflavinum/vitamin/).
