pyridoxine

water-soluble organic compound that is an essential micronutrient for microorganisms and animals. It occurs in three forms: pyridoxine (or pyridoxol), pyridoxal, and pyridoxamine. Pyridoxine was first isolated in 1938 and synthesized in 1939. Pyridoxal and pyridoxamine, which were discovered in the 1940s, are responsible for most of the vitamin B6 activity in animal tissues. Vitamin B6 is widely distributed in foodstuffs and is particularly abundant in cereal grains, meats, nuts, and some fruits and vegetables. The chemical structure of the vitamin B6 family is as follows:
