A three-residue peptide holding a copper ion, isolated originally from human plasma. Used to study copper-dependent enzyme activity, collagen and glycosaminoglycan synthesis in fibroblast culture, and metal-peptide coordination chemistry. The blue color is the copper; a lot that has gone pale has lost it.
