Glycyl-glycyl-glycine
Glycyl-glycyl-glycine, often referred to as triglycine, is a tripeptide composed of three glycine (Gly) amino acid residues linked together by peptide bonds.
Chemical Structure and PropertiesStructure: The tripeptide is formed by three glycine molecules connected through amide bonds (peptide bonds). Its chemical structure can be represented as:
H₂N-CH₂-CO-NH-CH₂-CO-NH-CH₂-COOH
The amino group (-NH₂) at the N-terminal and carboxyl group (-COOH) at the C-terminal are retained, making it a linear peptide.Glycine, the smallest amino acid, has a hydrogen atom as its side chain, giving triglycine a compact and flexible structure.
Molecular Formula:(C₆H₁₂N₃O₄）Molecular Weight: Approximately 189.18 g/molPhysical Properties: It is a white crystalline powder, soluble in water, and has a neutral pH in solution.
