Nicotinic acid is also called vitamin B3, or vitamin PP, molecular formula: C₆H₅NO₂, heat, can be sublimation. Nicotinic acid nicotinic acid, also known as antipellagra factor. In the human body including its nicotinamide or nicotinamide derivatives. It is one of the 13 essential vitamins, is a water-soluble vitamin, belonging to the family of vitamin B. Nicotinic acid into nicotinamide in the human body, nicotinamide is part of NADH and NADPH, involved in lipid metabolism in vivo, the process of the oxidation process and the anaerobic decomposition of sugar tissue respiration.

Nicotinic acid and nicotinamide are soluble in water and alcohol; properties of nicotinic acid and nicotinamide are relatively stable, acid, alkali, oxygen, light or heating conditions is not easy to be destroyed; under high pressure, 120 DEG C, 20min is not destroyed. General processing loss is very small, but it will be with the loss of water.

purpose

Nicotinic acid has a strong role in the expansion of peripheral blood vessels, clinical use for the treatment of headache, migraine headaches, tinnitus, inner ear vertigo, etc..

Nicotinic acid as vitamins, vitamin PP and nicotinamide collectively, for antipellagra, can also be used as a blood vasodilator used as food additives, feed. As for pharmaceutical intermediates, isoniazid, nicotinamide, Nikethamide and hexanicit production etc..

If the lack of time, can produce pellagra, manifested as dermatitis, glossitis, oropharynx, diarrhea and irritability, insomnia and other symptoms of paresthesia. Nicotinic acid is a relatively stable vitamin that is relatively stable in food, and is not affected by the loss of a large number of cooking and storage.

To promote the health of the digestive system, reduce gastrointestinal disorders; make the skin more healthy; prevent and relieve severe migraine; promote blood circulation, make blood pressure drop; relieve diarrhea.
