The Arabidopsis Book, 2011 Glutathione is a simple sulfur compound composed of three amino acids and the major non-protein thiol in many organisms, including plants. The functions of glutathione are manifold but notably include redox-homeostatic buffering. Glutathione status is modulated by oxidants as well as by nutritional and other factors, and can influence protein structure

Glutathione and mitochondria [PDF]
Frontiers in Pharmacology, 2014 Glutathione (GSH) is the main non-protein thiol in cells whose functions are dependent on the redox-active thiol of its cysteine moiety that serves as a cofactor for a number of antioxidant and detoxifying enzymes. While synthesized exclusively in the cytosol from its constituent amino acids, GSH is distributed in different compartments, including ...

GLUTATHIONE DETERMINATION AND A STUDY OF THE ACTIVITY OF GLUTATHIONE-PEROXIDASE, GLUTATHIONE-TRANSFERASE, AND GLUTATHIONE-REDUCTASE IN RENAL TRANSPLANTS [PDF]
Renal Failure, 2002 The aim of this work is to study the temporary variation of oxidative stress in renal transplants, both in plasma and in erythrocytes (CR). In order to do so, we determined total glutathione (GST) levels, both oxidized (GSSG) and reduced (GSH), and the activity of enzymes, glutathione peroxidase (G-px), glutathione reductase (G-red) and glutathione ...

Effect of a significant deficiency in some antioxidants on semen parameters in cases of male infertility in Diyala Province, Iraq [PDF]
Journal of Research in Applied and Basic Medical Sciences, 2023 Background & Aims: Scientific evidence indicates that oxidative stress (OS) is a major factor in the etiology of male infertility. OS occurs when there is an imbalance between reactive oxygen species (ROS) and protective antioxidants.

Oxidative Stress in Relation to Aging and Exercise
Encyclopedia, 2022 Oxidative stress is an imbalance between oxidants and antioxidants in favor of the oxidants, resulting in disruption of redox signaling and control and causing molecular damage.
