It is a keto carotenoid, fully known as 3,3 '- dihydroxy- β,β- Carotene-4,4 '- Dione.
*The end of the conjugated double bond chain has unsaturated ketone and hydroxyl structures, which is easy to react with and scavenge free radicals.
*Three optical isomers can be formed: left-handed (3S, 3 ´ s), racemic (3R, 3 ´ s) and right-handed (3R, 3 ´ R) structures. Only l-astaxanthin has strong antioxidant and other biological activities, and the biological activity of right-handed astaxanthin is low.
