What is Lycopene?

In plain words

Lycopene is a natural red pigment found in tomatoes and some other fruits. The body absorbs it along with dietary fat and carries it into tissues, but does not turn it into vitamin A. Researchers study its possible links to heart and prostate health. Human studies have not clearly shown that lycopene supplements prevent or treat disease.

Technical definition

Lycopene is a lipophilic, acyclic C40 carotenoid with 11 conjugated double bonds, naturally present in tomatoes, watermelon, and other red or pink fruits; unlike some carotenoids, it is not a vitamin A precursor. It has no established primary receptor target, but its conjugated structure enables singlet-oxygen quenching and other antioxidant effects in experimental systems. It is marketed as a dietary supplement rather than an approved treatment for disease.
