meso-Zeaxanthin
Xanthophyll carotenoid / From Wikipedia, the free encyclopedia
meso-Zeaxanthin (3R,3′S-Zeaxanthin) is a xanthophyll carotenoid, and is one of the three stereoisomers of zeaxanthin. Of these three stereoisomers, meso-zeaxanthin is the second most abundant in nature, after 3R,3′R-zeaxanthin, which is produced by plants and algae.[1] meso-Zeaxanthin has been identified in specific tissues of marine organisms[2] and in the macula lutea, also known as the "yellow spot", of the human retina.[3][4]
