Gradient of reduced glutathione in the tail of Hemidactylus leschenaultii (Sauria: Gekkonidae).

ABSTRACT

A proximo-distal gradient of reduced glutathione (GSH), a non enzymatic antioxidant was observed in the original tails of the lizard, H. leschenaultii. In the regenerating tails, a gradual increase in the level of GSH was noted with tail elongation. In the newly regenerated tails also the level of GSH remained higher in the proximal part than the corresponding distal parts.
