  • Name: pyridoxic acid
  • Description: 4-pyridoxic acid is 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. It has a role as a human metabolite and a mouse metabolite. It is a member of methylpyridines, a hydroxymethylpyridine, a monohydroxypyridine and a vitamin B6. It derives from an isonicotinic acid. It is a conjugate acid of a 4-pyridoxate. (CHEBI ID:17405)
