provitamin, beta-carotene

Explanation:

Beta-carotene is an example of a provitamin. It is a less active form of retinol (Vitamin A) that is synthesized by plants. Animals i.e. humans, cannot synthesize or make use of this form of Vitamin A. It can only be made available for use in humans through normal metabolic processes. Humans can access this provitamin by consuming food that is rich in beta-carotene. When beta-carotene undergoes normal metabolic processes in the body, it is transformed into retinol, which is an active form of Vitamin A. Vitamin A is needed by humans for healthy skin, good vision and eye health, as well as maintaining strong immune system.
