coli , oxidants promote S-glutathionylation of the MarR repressor (a MarR-family protein), reducing its DNA binding and derepressing the mar operon (including acrAB )
Notably, fat-soluble vitamins, particularly vitamin A, are indispensable for the production of the light-sensitive pigment rhodopsin in the retina, which is critical for both low-light and color vision
4 Four of the most critical are: Aging defense Antioxidant protection Detoxification Energy production Glutathione is also responsible for: Cysteine carrier/storage Cell signaling Enzyme function Gene expression Cell differentiation/proliferation Thats a lot of detailed medical and biochemical jargon that means, in short, the antioxidant properties of glutathione work to improve communication between the cells, stabilize, and reduce oxidation in the cells, fight free radical damage, support protein function, and take out the cellular trash
High levels of this enzyme point to more oxidative stress that needs to be neutralized [42, 43]
