Glutathione, an Antioxidant Tripeptide: Dual Roles in

WebGlutathione, although a tripeptide, contains a peptide bond that is formed by the γ-carboxyl group of glutamate rather than by the α - carboxyl group. The glutathione transport systems present in both poles of the enterocyte do not recognize normal dipeptides and tripeptides as substrates. WebThe simple and widely distributed tripeptide glutathione (first entry in the following table), is interesting because the side-chain carboxyl function of the N-terminal glutamic acid is used for the peptide bond. An N-terminal … future in my life

Glutathione is capable of preventing damage to important cellular components caused by sources such as reactive oxygen species, free radicals, peroxides, lipid peroxides, and heavy metals. It is a tripeptide with … See more Glutathione biosynthesis involves two adenosine triphosphate-dependent steps: • First, γ-glutamylcysteine is synthesized from L-glutamate and cysteine. This conversion requires the enzyme • Second, glycine is added to … See more Glutathione exists in reduced (GSH) and oxidized (GSSG) states. The ratio of reduced glutathione to oxidized glutathione within cells is a measure of cellular oxidative stress where increased GSSG-to-GSH ratio is indicative of greater oxidative stress. In … See more Systemic availability of orally consumed glutathione is poor because the tripeptide is the substrate of proteases (peptidases) of the alimentary canal, and due to the absence of a specific carrier of glutathione at the level of cell membrane.
