glutathione composition tripeptide cysteine glycine glutamate Structure of reduced (GSH) . Glutathione (L- g Glutathione: Overview of its protective

However, because the electrophiles are reactive, with a short lifespan, it is difficult to measure them directly in vivo

In fact, replenishing glutathione levels may improve cell function in diseases like ulcerative colitis and prevent further cell damage by protecting against the harmful effects of oxidative stress

The others proteins identified as differentially expressed were related to heme synthesis (Biliverdin reductase A) and antioxidant enzymes (Peroxiredoxin 6, Glutathione S-transferase P) which may reflect an increase of free radical levels and consequent induction of antioxidant enzymes to protect against apoptosis 32

Once Cu is in bile it forms an unabsorbable complex, possibly with certain bile acids, which is eliminated in stool ( Figure 1 ) (30)
