Antioxidant functions of carotenoids.
TL;DR: The many reports indicating that carotenoids may possess some anticarcinogenic properties may well be related to their ability to interact with and quench various radical species that can be generated within cells.

Antioxidant Action of Carotenoids
TL;DR: The focus is on the ability of beta-carotene to function as a chain-breaking antioxidant in a lipid environment at physiological O2 partial pressures, the mode considered most likely to operate in mammalian cells.
