The 4-carboxyaldehyde form of vitamin B6, it is converted into pyridoxal phosphate, a coenzyme for the synthesis of amino acids, neurotransmitters, sphingolipids and aminolevulinic acid. | pyridoxal |
| pyridoxal phosphate | The monophosphate ester obtained by condensation of phosphoric acid with the primary hydroxy group of pyridoxal. | pyridoxal 5'-phosphate |
| pyridoxal phosphate-6-azophenyl-2',4'-disulfonic acid | An arenesulfonic acid that is pyridoxal 5'-phosphate carrying an additional 2,4-disulfophenylazo substituent at position 6. | 5'-phosphopyridoxal-6-azobenzene-2,4-disulfonic acid |
| pyridoxamine | A monohydroxypyridine that is pyridine substituted by a hydroxy group at position 3, an aminomethyl group at position 4, a hydroxymethyl group at position 5 and a methyl group at position 2. The 4-aminomethyl form of vitamin B6, it is used (in the form of the hydrochloride salt) for treatment of diabetic nephropathy. | pyridoxamine |
| pyridoxamine phosphate | A vitamin B6 phosphate that is the phosphoric ester derivative of pyridoxamine. | pyridoxamine 5'-phosphate |
| pyridoxic acid | A methylpyridine that is 2-methylpyridine substituted by a hydroxy group at C-3, a carboxy group at C-4, and a hydroxymethyl group at C-5. It is the catabolic product of vitamin B6 and is excreted in the urine. | 4-pyridoxic acid |
| pyridoxine | A hydroxymethylpyridine with hydroxymethyl groups at positions 4 and 5, a hydroxy group at position 3 and a methyl group at position 2. The 4-methanol form of vitamin B6, it is converted intoto pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters, sphingolipids and aminolevulinic acid. | pyridoxine |
| pyrithione | A pyridinethione that is pyridine-2(1H)-thione in which the hydrogen attached to the nitrogen is replaced by a hydroxy group. It is a Zn(2+) ionophore; the zinc salt is used as an antifungal and antibacterial agent. | pyrithione |
