Nicotinamide Usage And Synthesis

B vitamins	Nicotinamide is also called vitamin B3 or vitamin PP, is a kind of water-soluble vitamin, belong to B vitamin, as NAD (nicotinamide adenine dinucleotide, NAD) and NADP (nicotinamide adenine dinucleotide phosphate, NADP) composition, hydrogenation and dehydrogenation properties of nicotinamide in the body part of this two kinds of structure of coenzyme the reversible, play a role of hydrogen delivery in biological oxidation, can promote tissue respiration, biological oxidation process and the new supersedes the old, having a great significance in maintaining normal tissue, especially the integrity of the skin digestive tract and the nervous system. When the lack of B vitamins, due to respiration and metabolism of cells affected by pellagra, so this product is mainly used for the prevention and treatment of pellagra, stomatitis, glossitis and so on. In addition, this product has prevention of heart block and improving the sinoatrial node and anti-fast experimental arrhythmia function, can significantly improve Vera Pammy induced bradycardia and atrioventricular block. The clinical for coronary heart disease, viral myocarditis, rheumatic heart disease and a handful of digitalis poisoning associated with arrhythmia (mostly applied only when other medications fail), generally the degree atrioventricular block has obvious curative effect, basically after the treatment, all block can disappear, has obvious curative effect in sick sinus syndrome, right bundle branch block effect is poor. After the stomach intestinal absorption by the oral, intramuscular absorption faster, then absorption distribution to the body tissues, t1/2 is 45 min. The liver metabolism, most metabolize N- n-methylnicotinamide, only a small amount of treatment as the prototype from the urine was more than necessary. If the daily urinary excretion of N- methyl nicotinamide is lower than 4mg, suggesting that nicotinamide deficiency. Nicotinamide and nicotinic acid are collectively referred to vitamin PP, nicotinic acid in the animal body is involved in metabolic processes in the form of nicotinamide, both have a common vitamin activity. It is white crystalline powder, odorless or almost odorless, bitter taste, easily soluble in water or ethanol, soluble in glycerol. Hygroscopic weak stable., acid, alkali and high temperature. The nature mainly exists in cereal skin, yeast, peanuts, meat, animal organs, milk and green leafy vegetables, in the body it is from tryptophan synthesis, but the efficiency is very low. Escherichia coli in the intestine (Escherichia coli) can be converted into synthesis of nicotinic acid, nicotinamide. Prevention and treatment of pellagra, exposed parts of symmetric dermatitis, stomatitis, glossitis, anorexia, dermatitis, liver disease, coronary heart disease, atrioventricular block, sick sinus syndrome, diarrhea, neuritis and dementia. [Adverse reaction] Occasionally dizziness, nausea, abdominal discomfort, loss of appetite, disappear on their own, in early pregnancy overdose possible teratogenic intramuscular injection can cause pain, so less.

General Description	White powder.
Air & Water Reactions	Water soluble.
Reactivity Profile	An amine and amide. Acts as a weak base in solution. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
