The term vitamin B6 is a generic term for three chemical compounds that are largely similar and belong to the vitamin B complex group. It occurs as a phosphoric acid ester, aldehyde, alcohol or amine.
Like other vitamins, the organism cannot produce vitamin B6 on its own and has to rely on food for it.
Vitamin B6 is often referred to as pyridoxine. It is a vitamin with high water solubility that is very sensitive to sun exposure or heat.
This is why food quickly loses the required value of vitamin B6, which a person has to absorb through food, during cooking or if it is not stored in the dark.
