Knowra Vitamin B6 Vitamin B6 Vitamin B6 is a group of related compounds, including pyridoxine, that the body converts into coenzymes used in amino acid metabolism, neurotransmitter synthesis, and other processes.
Pyridoxal 5′-phosphate : The principal active coenzyme form of vitamin B6 in human tissues. This form carries out most vitamin B6-dependent reactions.
Dietary Reference Intake : A set of nutrient intake reference values used to assess and plan diets. Its vitamin B6 recommendations vary by age, life stage, and national authority.
Pyridoxine : A vitamin B6 vitamer found especially in plant foods and commonly used in supplements. It is the B6 form named in the concept's definition.
Vitamin B12 : A water-soluble vitamin required for red blood cell formation, neurological function, and DNA synthesis. B12 deficiency can also cause neurological and blood abnormalities, but has different causes and treatments.
Aminotransferase : An enzyme that transfers an amino group between an amino acid and a carbonyl compound. Many aminotransferases require pyridoxal 5′-phosphate to transfer amino groups.
Vitamin B6 deficiency : A state in which vitamin B6 availability is insufficient for normal physiological functions. Deficiency can impair blood-cell formation, skin health, and nervous-system function.
Pyridoxal : An aldehyde-containing vitamin B6 vitamer found in foods and formed during B6 metabolism. It is phosphorylated to form the principal active B6 coenzyme.
Folate : A B vitamin needed for one-carbon transfers, nucleotide synthesis, and cell division. Folate shares one-carbon metabolism with B6 but uses different coenzyme chemistry.
Decarboxylation : A chemical reaction that removes a carboxyl group, releasing carbon dioxide. B6-dependent decarboxylases produce several neurotransmitters from amino acids.
Vitamin B6 toxicity : Harmful effects caused by excessive vitamin B6 exposure, especially from supplements. Prolonged high-dose intake can cause sensory neuropathy.
