| | Glycyl-glycyl-glycine Usage And Synthesis |
| Chemical Properties | white crystalline powder | | Uses | Substrate for tripeptide aminopeptidase. | | Uses | Glycyl-glycyl-glycine is used as a model peptide for studies of physicochemical parameters and molecular associations of small peptides. It is also used as a copper chelator. | | Definition | ChEBI: A tripeptide in which three glycine units are linked via peptide bonds in a linear sequence. | | General Description | Gly-Gly-Gly or triglycine is a flexible peptide linker with three glycine residues linked by peptide bonds in a linear sequence. Gly-linkers link multiple domains in a single protein without affecting the function of each domain. | | Biochem/physiol Actions | Substrate for reproducible serum protein measurements by the biuret reaction and for the assay of aminotripeptidases. | | Purification Methods | Crystallise triglycine from H2O or H2O/EtOH and dry it at 110o.
