Evaluation of TBARS levels after the induction of oxidation by CuCl2 (0.1 mM) in serum and liver homogenate of male
Wistar rats. Parts (A) and (B) represent the concentration–response curves of the production of TBARS induced by CuCl2 in the
presence of different carotenoids. Results are presented as m ean7 S.E.M. of 5 experiments conducted in triplicate. * Po0.05 is
statistically different when compared to synthetic astaxanthin. ASX ¼ synthetic astaxanthin; TC CS ¼ total carotenoids
extracted from control shrimp; TC SS ¼ total carotenoids extracted from supplemented shrimp.
