Vitamin PP (niacin) plays an important role in metabolic processes (proteins, fats, carbohydrates, amino acids, cholesterol), accelerates the oxidation-reduction reactions, is included in several coenzymes affects the cardiovascular, nervous and digestive systems. It is vital for the synthesis of sex hormones. The main representatives of this group include nicotinic acid and nicotinamide.
