glutathione reductase deficiency anemia synthetase The Redox Process in Red

HbF has a tendency to denature with oxidative stress and precipitate to disrupt the RBC membrane, contributing to the shortened RBC lifespan

Additionally, it regulates melanin production, a pigment which triggers hyperpigmentation and dark spots, and gives brighter skin

demonstrated the use of transdermal delivery of glutathione by loading it into the hyaluronic acid microneedles.[] GLUTATHIONE POLYMER FILMS Recent research focuses on the use of GSH responsive linkers to prepare polymers which degrade upon the exposure to millimolar concentrations of GSH, and the use of these polymers to prepare particles that disassemble at these concentrations

In other words, the biological advantage of protecting somatic cells in old age will not have a major impact on survival of the species, whereas energy expended at younger ages will be a strong selective advantage
