Vitamin A for healthy eye vision.

Vitamin A is a group of fat soluble organic compound that includes retinol, retinal and retinyl Ester and Pro vitamin A carotenoids like beta–carotene.

There are two forms of Vitamin A that are found in food.

1:- The source of vitamin A that obtained from animal is either retinol or bound to fatty acid to become a retinyl Easter.

Retinol is converted into retinal that is the most active form of Vitamin A, with the help of an enzyme called alcohol dehydrogenase.

Vitamin A is stored in human liver in the form of retinyl Ester.

2:- another source of Vitamin A which come from plants are carotenoids. There are more than 600 different types of carotenoids, but few carotenoids that can be converted into vitamin A in our body. They are :- Alpha— carotene, beta—carotene,gamma—carotene and beta—cryptoxanthin.
