Main application:
Nicotinic
acidcontraco belongs to the vitamine B. Which consists of all the
pyridine-3-hydroxy acid and their ramification.It mainly exists in the animal's
body in the form of niacinamide. nicotinic acid has the best structure and the
most steady physicochemical property of all the vitamins. It is safe from the
damage of acid, alkali, moisture, meallic ion, heat, light oxidant in
manufacture or storage.
Nicotinic acid and niacinamide are of the same vitamin activity. Human beings
body will get pellagra desease dueing lack of nicotinic acid. In medical
treatment, nicotinic acid is used for pellagra,glossitis, stomatitis, also used
in the prevention and cure for other skin diseases. Nicotinic acid is an
effective medicine in the prevention and cure for angiocardiopathy, which can
boost metabolism and reduce plasma triglyceride to restrain the cholesterin.
Recently, nicotinic acid has been well developed as a main element of
nutrition, food and feed supplement. Generally, there is not enough nicotinic
acid in feedstuff to meet the need of animal body. When making nicotinic acid
as a nutritious feed supplement, which is effective in boosting animals
development and prevention and cure pellagra.
Nicotinic acid is also widely used in medicine, chemical industry and
electroplate field.
