The structure of the glutathione is Explain the function of glutathione as a free radical scavenger in the cells.

Free radical scavengers are similar to the secondary antioxidants used to inhibit thermal oxidation. They react with free radicals in the cells, reducing them to stable, unreactive products. Glutathione acts as a free radical scavenger in the cells, due to the presence of - CH 2 SH group. This group reduces the free radicals like ∙ OH to H 2 O and itself oxidised to a disulphide. 2 R - SH + 2 ∙ OH ⇌ R - S - S - R + H 2 O
