Reaction of Astaxanthin with Peroxynitrite [PDF]

Bioscience, Biotechnology, and Biochemistry, 2008
The in vitro reactivities of astaxanthin toward peroxynitrite were investigated and the reaction products after scavenging with peroxynitrite were analyzed in order to determine the complete mechanism of this reaction. A series of carotenoids, 13-apo-astaxanthinone (1), 12'-apo-15'-nitroastaxanthinal (2), 12'-apo-astaxanthinal (3), 10'-apo ...
