Understanding the Gly His Peptide Structure
The dipeptide Gly-His (Glycyl-L-histidine) is composed of glycine (Gly) and L-histidine (His) joined by a peptide linkage. With the molecular formula C8H12N4O3, this compound is often studied for its role as a metabolite and its unique chemical properties. When examining the fully proton Gly-His = 99.0 AT calc. based on dry substance 3486-76-8 ated structure of Gly–His dipeptide, researchers look at the N-terminus (NH3+), Glu-Gly-His| C13H19N5O6 | CID 145455377 - structure, chemical names, physical and chemical properties, classification, patents, literature, the backbone amide (neutral), the C-terminus (COOH), and the histidine side chain (imidazolium).
Understanding these structures is essential for anyone interested in the specific interactions of peptides. The simple glycine amino acid, being the most basic of all residues, provides the structural flexibility necessary for these sequences to function efficiently in various model systems.
The Significance of GGH and Copper Complexation
Perhaps the most notable member of this family is Gly-Gly-His (GGH) tripeptide. Often referred to as Gly-Gly-His-OH, this molecule is widely recognized for its ability to bind to copper (Cu2+) and form a stable complex. This property makes it a subject of fascination for those studying metal-chelating agents.
From my personal observations in laboratory settings, the Gly-Gly-His is a peptide that binds to copper and forms a complex with remarkable precision. This affinity is not limited to copper; researchers have noted that H-Gly-His-OH also forms complexes with other metals, such as Au (III) and Pd (II). The precision of these interactions is why global suppliers, such as the Peptide Institute, Inc., provide high-purity samples for biochemical applications.
