Thiamine, Thiamine or Vitamin B1 is a water-soluble vitamin of the B complex,Thiamine is used in the biosynthesis of the neurotransmitter acetylcholine and gamma-aminobutyric acid (GABA). In yeast, TPP is also required in the first step of alcoholic fermentation.
All living organisms use thiamine, but it is synthesized only in bacteria, fungi, and plants. Animals must obtain it from their diet, and thus, for us, it is an essential nutrient. Insufficient intake in birds produces a characteristic polyneuritis. In mammals, deficiency results in Korsakoff's syndrome, optic neuropathy, and a disease called beriberi that affects the peripheral nervous system (polyneuritis) and/or the cardiovascular system. Thiamine deficiency has a potentially fatal outcome if it remains untreated.
Vitamin B1 is also called thiamine or fight neuritis vitamins or resistance beriberi, white crystal, the presence of oxidants easily by oxidative dehydrogenation thiamine, which appear blue fluorescence under uv irradiation.:
It was the first vitamin found.A group of B vitamins composed of pyrimidine ring and thiazole ring bound by methylene.White crystalline or crystalline powder;It has a weak odor, bitter taste, and can induce moisture. It is easy to absorb water when exposed to air.It is easy to decompose and deteriorate in alkaline solution.Ph 3.5 to 100 ℃ high temperature resistant, acid and alkali easy failure is greater than 5.Light and thermal titer drop.Therefore should be placed in the shading, cool preservation, not long storage.Stable in acid solution, unstable in alkaline solution, easy to be oxidized and damaged by heat.Reducing substances such as sulfite and sulfur dioxide can deactivate vitamin B1.
As a feed additive, vitamin B1 plays an important role in maintaining normal nerve conduction and normal activities of the heart and digestive system.When livestock and poultry lack, easy to produce carbohydrate metabolism disorder, appetite loss.Dosage of 20 to 40 g/t.It is suitable for vitamin B1 deficiency, with the function of maintaining normal glucose metabolism and nerve conduction, as well as the auxiliary treatment of dyspepsia and neuritis.
