Copper Peptides and Coordination Chemistry: How a Metal Binds a Peptide

Copper peptides are among the most widely discussed metal–peptide complexes in biochemical research. A well-known example is GHK-Cu, a complex formed when the naturally occurring tripeptide GHK (glycyl-L-histidyl-L-lysine) binds with a copper(II) ion. Understanding copper peptides coordination chemistry provides insight…
