Serum γ-glutamyltransferase as Oxidative Stress Marker in Pre-and Postmenopausal Iraqi Women.

Objectives: The primary role of γ-glutamyltransferase is to metabolize reduced glutathione by assimilating and utilizing precursor amino acids for intracellular glutathione synthesis. The aim of this study is to investigate the exact role of γ- glutamyltransferase enzyme in the oxidative stress associated with menopause.

Methods: This study was carried out at the Chemistry and Biochemistry department, Al-Nahrain University from October 2009 to January 2010.
