Vitamin B6 occurs in three forms, pyridoxine, pyridoxal, and pyridoxamine. B6 is absorbed in the large intestine. The muscle stores approximately 75-80% of vitamin stores while phase approximately 5-10%.
B6 is required for transaminations of decarboxylation of dehydratase, reactions of side chain cleavage, and release of ammonia. Her group of aldehyde acts as a Schiff base to react with amino groups of amino acids. It basically acts to shuttle between the nitrogen compounds.
Functions
The three forms of B6 can all be converted to coenzyme PLP, which facilitates the transamination and the metabolism of proteins. PLP is essential for the degradation of glycogen, it also helps with the formation of the neurotransmitter, serotonin, in part, without protein hemoglobin (heme), nucleic acids, and lecithin. Vitamin B6 is essential for the metabolism of tryptophan to niacin. (more…)
