Aim
1.To prepare a cpmplex of g;ycine with copper.
Introduction
The amino acid glycine is one of approximately twenty naturally-occurring amino acids that are used as the building blocks of proteins in biological systems.It can dissociate by loss of a proton to form the glycinate mono-anion(gly)which can act as a bidentate ligand by coordinating through a carboxylate O atom and the amino N atom.Many proteins and enzymes(in living things)have one or more metal ions bound to them which are essential for their activity.Understanding the function of metalloproteins.
