Vitamin B6 is required for the majority of biological reactions (amino acid metabolism, neurotransmitter synthesis, red blood cell formation).
It occurs in three forms: pyridoxal, pyridoxine, and pyridoxamine. All can be converted to the coenzyme PLP (pyridoxal phosphate), that transfers amino groups from an amino acid to make nonessential amino acids, an action that is valuable in protein and urea metabolism. The conversions of the amino acid tryptophan to niacin or to the neurotransmitter serotonin also depend on PLP. In addition, PLP participates in the synthesis of the hemecompound in hemoglobin, of nucleic acids in DNA and of lecithin, a fatty compound (phospholipid) that provides structures to our cells.
Vitamin B6 is stored in muscle tissue.
