Description

Application

<ul>
<li><strong>Lutein in cellular antioxidant research:</strong> A study conducted by Lakshminarayana et al. investigates the oxidative derivatives of lutein in cellular environments using HeLa cells. The research focuses on lutein′s role as an antioxidant and its cytotoxic effects when exposed to oxidative stress, crucial for understanding its therapeutic potential in disease contexts where oxidative stress plays a role (Chemico-biological Interactions, 2013).</li>
<li><strong>Lutein in photosystem II research:</strong> Lutein binds violaxanthin, neoxanthin or zeaxanthin and even in the absence of zeaxanthin, plays a crucial role in the energy transfer processes within photosystems (European Journal of Biochemistry, 2001).</li>
</ul>

Biochem/physiol Actions

Dietary carotenoid with no vitamin A potency. Increases macular pigment concentration in the eye and may improve visual function.
