Nutrition as well as diet – Vitamin B6

  • Listed: Nisan 15, 2021 6:48 am


Vitamin B6 occurs in three forms–pyridoxine, pyridoxal, and pyridoxamine. B6 is absorbed in the large intestine. The muscle stores more or less 75 80 % of the vitamin although the living stores approximately 5 10 %.

B6 is required for transaminations, ammonia release,, side-chain cleavage reactions, dehydratases and decarboxylations. Its aldehyde group works as a Schiff base to react with the amino groups of amino acids. It essentially acts to shuttle nitrogen among compounds.
Functions- The 3 sorts of B6 could all be converted to the coenzyme PLP which aids in transamination and protein metabolism. PLP is essential for glycogen degradation; it also helps with the development of the neurotransmitter, serotonin, the nonprotein part of hemoglobin (heme), nucleic acids, and lecithin. Vitamin B6 is essential for the metabolism of tryptophan to niacin.

Overall Reactions:
· Transaminations These responses are keto pills worth it – browse this site – http://matroska.net/user/profile/46873, required to recycle and reuse nitrogen – http://www.theepochtimes.com/n3/search/?q=reuse%20nitrogen within the body. They are the initial step of amino acid catabolism and the very last phase in the synthesis of nonessential amino acids. Example: a-ketoglutarate + asparate glutamate + oxaloacetate

· Serine/ Threonine Deamination (Dehydratases) This reaction offers the generation of the a-keto acids of threonine as well as serine through oxidative removal of N as ammonia Example: Serine a-keto-serine + NH4+
· Decarboxylation These reactions often occur on the neuroactive amines of seratonin, tyramine, histamine, and GABA. They also are critical in porphyrin synthesis, intermediates in the synthesis of sphingomyelin, taurine and lecithin, as well as for the breakdown and desulfuration of cysteine.
· Glycogen Phosphorylase 50 % of all B6 in the body is bound to glycogen phosphorylase but the importance is unknown. The reaction is important for recycling of folate and is as follows:
