Antheraxanthin(CAT: R066538) is a xanthophyll carotenoid found in various plants, algae, and photosynthetic organisms. It plays a crucial role in the xanthophyll cycle, a process that protects plants from oxidative damage caused by excess light energy during photosynthesis. Antheraxanthin is an intermediate in the conversion of violaxanthin to zeaxanthin, both of which are involved in non-photochemical quenching, a mechanism that dissipates excess light energy as heat to prevent photoinhibition. Beyond its role in photoprotection, antheraxanthin has been studied for its antioxidant properties and potential health benefits, including its contributions to eye health and its anti-inflammatory effects. Its presence in the human diet, primarily through the consumption of leafy greens and other vegetables, contributes to overall health and well-being.
