As well as Nutrition – Supplement B6

Vitamin B6 occurs in 3 forms–pyridoxine, pyridoxamine, and pyridoxal. B6 is absorbed inside the large intestine. The muscle stores roughly 75-80 % of the vitamin although the live stores approximately 5 10 %.

B6 is necessary for transaminations, ammonia release,, side-chain cleavage reactions, dehydratases and decarboxylations. Its aldehyde group functions as a Schiff base to react with the amino groups of amino acids. It essentially acts to shuttle nitrogen between compounds.

Functions- The three forms of B6 can all be switched into to the coenzyme PLP which helps in transamination and protein metabolism. PLP is essential for glycogen degradation; additionally, it will help with the development of the neurotransmitter, serotonin, the nonprotein part of hemoglobin (heme), nucleic acids, and lecithin. Vitamin B6 is important for the metabolic process of tryptophan to niacin.

General Reactions:

· Transaminations These responses are needed to recycle and reuse nitrogen in the entire body. They’re the initial phase in amino acid catabolism as well as the very last phase in the synthesis of nonessential amino acids. Example: a-ketoglutarate + asparate glutamate + oxaloacetate

· Serine/ Threonine Deamination (Dehydratases) This reaction supplies the production of the a-keto acids of threonine and serine through oxidative removal of N as ammonia Example: Serine a-keto-serine + NH4+

· Decarboxylation These reactions typically appear on the neuroactive amines of GABA., histamine, tyramine, and seratonin They also are important in porphyrin synthesis, intermediates inside the synthesis of sphingomyelin, taurine and lecithin, and for the breakdown and desulfuration of cysteine.

· Glycogen Phosphorylase fifty % of all B6 inside the body is bound to glycogen phosphorylase however, the importance is unknown. meal service delivery is crucial for recycling of folate and is as follows:

Serine glycine + 5,10-methylene-THF

Deficiency Deficiencies of vitamin B6 are rather rare. Individuals with a diet lacking in vitamin B6 will 1st show signs of weakness, irritability, insomnia, nervousness, and hydrated skin lesions. Far more advanced symptoms consist of growth failure, impaired motor function, hypochromic microcytic anemia, smooth tongue, along with convulsions.

The impaired motor function along with other mental problems could be attributed to a decrease in amino acid-based neurotransmitters (serotonin, GABA, tyramine, epinephrine). You see a rise in urea excretion due to a decrease synthesis of nonessential amino acids. The nitrogen from these amino acids is not reused by transamination and instead is excreted and lost. You see a rise in urinary excretion particularly inside the next amino acids: metabolites of glycine, tryptophan, and methionine. The hypochromic microcytic anemia is simply because that there’s a lowered synthesis of the B6 dependent porphyrin ring of hemoglobin.

Individuals who are at most risk would be the aged with poor vitamin intake, alcoholics, hemodialysis patients, and those people that are on drug therapy. General, individuals with a high metabolic stress.

Sources Foods richest in vitamin B6 include:

o whole grains o legumes o nuts o navy beans o walnuts o meat (sirloin plus chicken) o fish (salmon and shellfish) o bananas along with apples o broccoli and spinach

Therapeutics Vitamin B6 might provide healing advantages due to the following syndromes: carpal tunnel syndrome, glucose intolerance, sideroblastic anemia, neurologic problems, hyperoxaluria, convulsive seizures, monosodium glutarate (MSG) intolerance, premenstral syndrome (pms) and Immune function. In addition, vitamin B6 may well help decrease homocysteine levels and hence the chance of developing cardiovascular disease.
