Tripeptide - Wikipedia
WEBA tripeptide is a peptide derived from three amino acids joined by two or sometimes three peptide bonds. [1] As for proteins, the function of peptides is determined by the constituent amino acids and their sequence. In terms of scientific investigations, the dominant tripeptide is glutathione (γ- L -Glutamyl- L -cysteinylglycine), which serves ...
Tripeptide - an overview | ScienceDirect Topics
WEBThe tripeptide glutathione (GSH), which plays an important role in the maintenance of the intracellular thiol redox state and in detoxification processes, is intracellularly regulated by glutathione reductase. The first and rate limiting step in the synthetic pathway is catalyzed by γ-glutamylcysteine synthetase (γ-GCS) ( Fig. 16 ).

WEBDec 21, 2002 · Tripeptides have been classified into three categories: rigid, non-rigid and intermediate, based on the relative structural rigidity between C α and C β atoms in a tripeptide. We found that 18% of the tripeptides in the dataset can be classified as rigid, 4% as non-rigid and 78% as intermediate.
