Antioxidants neutralize free radicals by donating an electron, thereby reducing their harmful effects on the body. Common antioxidants include vitamins C and E, beta-carotene, and selenium. **

The hydrolysis of glutathione is the process in which glutathione, a tripeptide composed of the amino acids glutamine, cysteine, and glycine, is broken down into its individual amino acid components through the addition of water. This process is catalyzed by the enzyme gamma-glutamyltransferase, which cleaves the gamma-glutamyl bond in glutathione. The resulting amino acids can then be used for various metabolic processes within the body. **
