Thiamin

Thiamin, also known as Vitamin B₁ has chemical formula C₁₂H₁₇ON₄SCl*HCl

It's colourless, soluble in water, insoluble in alcohol. It decomposes if heated.

Thiamin is coenzyme of pyruvate dehydrogenase, α-ketoglutaran dehydrogenase and transketolase. Because first two of these enzymes are important in metabolism of carbohydrates, Thiamin deficite causes problems with it. Thiamin deficit also causes the deseases of paresis and Beri-Beri.

Thiamin is also used, in quantities much higher than natural organism's requirements, as medicine against nerves inflammation.
