L-Glutathione (gamma-L-Glutamyl-L-cysteinyl-glycine) is a tripeptide composed of the amino acids L-glutamine, L-cysteine, and glycine. Glutathione is part of the antioxidant defense system of the cell, together with superoxide dismutase, catalase, glutharedoxin, thioredoxin, alpha-D-tocopherol (vitamin E), ascorbic acid (vitamin C), and others. GSH protects cells by neutralizing (i.e., reducing) Reactive Oxygen Radicals (ROS*).  This conversion is illustrated by the reduction of peroxides: 2 GSH + R2O2 → GSSG + 2 ROH (R…
