Vitamin B5 or pantothenic acid is water-soluble, it is thus lost in cooking water.
It is resistant to oxidation and light but destroyed by heat (thus denatured during cooking).
As the body does not produce it on its own, dietary sources are necessary.
Uptake takes place in the intestine, but the vitamin is not stored by the body. Every day, a sufficient amount of vitamin B5 must be obtained from dietary sources to cover the body's requirements.

Roles
