What are carotenes and xanthophylls?
Definition. Carotene refers to an orange or red plant pigment, including beta-carotene found in carrots and many other plant structures while xanthophyll refers to a yellow or brown carotenoid plant pigment which causes the autumn colors of leaves. Thus, this is the main difference between carotene and xanthophyll.
What is carotene in skin?

What is the difference between carotene and xanthophyll?
The major difference between xanthophylls and carotenes is that xanthophylls contain oxygen atoms in the form of a hydroxyl group or epoxides while carotenes are molecules with only hydrocarbons and no oxygen. Yellow corn contains various pigments and primarily xanthophylls and some amount of carotenes (Swallen, 1942).
What color do carotenoids reflect?
Plants of different colors contain other pigments, such as anthocyanins, which are responsible for reds and purples; anthoxanthins, which reflect yellow; and carotenoids, which reflect yellow, orange, or red. When plants change colors in autumn, it is due to their having a mixture of these pigments.
