Question

explain the relationship between cholesterol in the skin ans vitamin D

Answer 1

Ans:-

Relationship between cholesterol in the skin and vitamin D is as follows:-

- Vitamin D is linked with cholesterol because cholesterol in the skin is necessary to make vitamin D from the sunlight.

- Vitamin D is a fat soluble vitamin.

- During the formation of Cholesterol ,it forms 7- dehydrocholesterol as an intermediate and on exposure of sunlight this 7- dehydrocholesterol is converted to cholecalciferol (vit.D) in the skin.

- Then this cholecalciferol is converted to calcidiol in the liver.

- And then this calcidiol is converted to calcitriol by the kidneys ,and this calcitriol is the biologically active form of the vitamin D.

So , basically cholesterol in the skin is very necessary for the production of vitamin D by the sunlight.
