Clinical Use:
|
Beta-Carotene is the most common and effective provitamin A. This and other carotenoid compounds constitute the yellow-orange pigments of most vegetables and fruits. Dietary beta-carotene is converted by enzymes in the small intestinal mucosa to vitamin A. Carotenaemia resulting from excessive intake of carotene-rich foods, especially carrots, causes yellowing of the skin which is not injurious since excess carotene is deposited rather than converted to vitamin A |
