Cu2+ Complexes with the Simplest Amino Acid Glycine (Gly)

Abstract

Most Biology/Chemistry/Physicists and Medicinally related researchers think that the commonly known 20 Amino acids (AA) have been studied to the extent that they know almost everything about them. We believe that studying the simplest amino acid Glycine (Gly) is not that simple when it comes to its reactions with metal ions especially in aqueous solutions under ambient conditions. It is known that Gly is an inhibitory neurotransmitter [1-3]. Typically a 70 kg human body contains about 280 mg copper (Cu2+). The copper ion concentration in seawater is in the range of one micro-molar or (1.0x10-3 mM), while the human Extracellular Blood Plasma concentration of Cu2+ is ~1.5 x10-2 mM [1].
