Why Triglycine Was Selected as a Species of Interest
In my experience, when researchers look for a s by H Li · 2017 · Cited by 25 — Extensive ab initio investigations have been performed to characterize stable conformers of protonated triglycine (GGGH) in the gas phase. table, well-defined control, triglycine was selected as a species of interest primarily because of its Triglycine (glycyl-glycyl-glycine) BP EP USP CAS 556-33-2, also known as GGG, is a synthetic peptide with the molecular formula C9H17N3O6. Its Cas Number is predictable behavior. Unlike more complex molecules, the lack of chiral centers in glycine means that the resulting tripeptide does not suffer from the same stereochemical complexities as other peptides.
It is important to differentiate this from Glycylglycine, which is the dipeptide of glycine and often is usually used in the synthesis of more complex peptide chains. While related, the transition from a dipeptide to a tripeptide significantly alters the physical properties, including solubility and binding affinity in ligand-based assays.
