C. Cholesterol
D. Phenylalanine

Respuesta :

I believe the answer is 

A. Retinol

Carotenoids are converted to vitamin A in the body.

A set of compounds that have the biological activity of retinol is known as vitamin A.

Provitamin A is made up of a series of natural pigments called carotenoids (similar to carotene) that are capable of converting into vitamin A.

  • The main provitamin A carotenoid is β-Carotene, which is made up of two retinal molecules.

  • Hundreds of different carotenoids are synthesized by plants, but only about 10% of them are capable of being converted to retinol.

  • The provitamin A carotenoids that manage to enter the intestinal wall can pass intact to the lymphatic circulation, be excised and converted into retinoids (and continue their passage to the liver) or be stored intact until the cell is shed.

Therefore, we can conclude that carotenoids are converted to vitamin A in the body.
