An overview of astaxanthin determination in marine biological samples
Astaxanthin (AX) (3,3’dyhydroxy-β,β-carotene-4,4´dione) is a pigment that belongs to the family of the xanthophylls, the oxygenated derivatives of carotenoids whose synthesis in plants derives from ly- copene. AX, which may not be synthesized de novo by animals, is one of the main pigments in marine...
