COMPARISON OF ANTIOXIDANT EFFECT OF GLUTATHIONE AND ASTAXANTHINE IN THEIR THERAPEUTIC RANGE USING IN- VITRO METHODS

Now a days ,free radicals and antioxidants seek a great deal of attention.  Free radicals  are produced  naturally in our body by various endogenous reactions. However at higher concentrations, they can cause cell membrane , DNA and protein damage leading to various immunopathological states like inflammatory diseases, cancer hypertension, diabetes mellitus, atherosclerosis, ageing etc .An antioxidant is a stable molecule which donates its electron to a rampaging free radical and thus neutralizes its effect. Imbalance between free radicals and antioxidants leads to a condition called oxidative stress. Antioxidants can be endogenous or exogenous. Various dietary antioxidant supplements are  available commercially. The objective of this study is to compare the  antioxidant effect of  glutathione  and  astaxanthine  in their therapeutic  range using in- vitro methods
