Description
Water-soluble vitamin B6 represents a group of vitamins: pyridoxine, pyridoxal, and pyridoxamine, which are closely related and act together. It is found in large quantities in foods such as brewer's yeast, wheat bran, wheat germ, liver, kidneys, heart, melon, cabbage, milk, eggs, and beef. It acts as a coenzyme in metabolic reactions associated with the conversion of proteins, fats, and carbohydrates; its main function is participation in the synthesis of adrenaline, serotonin, and other neurotransmitters, nicotinic acid, glycogen breakdown, and amino acid metabolism.
The vitamin is necessary for the normal functioning of the central and peripheral nervous system. Upon entering the body, it is phosphorylated, converted into pyridoxal-5-phosphate, and becomes part of enzymes that carry out decarboxylation and transamination of amino acids. Pyridoxine actively participates in the metabolism of tryptophan, methionine, cysteine, glutamic acid, and other amino acids. It also plays an important role in histamine metabolism. Pyridoxine participates in fat metabolism processes, improving lipid metabolism in atherosclerosis, and takes part in the synthesis of heme, a component of erythrocyte hemoglobin.
Vitamin B6 deficiency can lead to pathological conditions such as growth retardation in children, cerebral convulsions (especially convulsive seizures in children), seborrheic dermatitis, meteorism, and peripheral neuritis.
