实验：甘氨酸合铜的制备（急需英译汉）
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.

实验目的
制备甘氨酸合铜
实验介绍
甘氨酸是生物界用来组建蛋白质的约20种天然氨基酸之一,它能够电离出一个质子得到甘氨酸根阴离子,该阴离子可以通过一个羧基氧原子和氨基氮原子起到二合配位体的作用.很多种蛋白质和酶（生物体内）结合着一至多个金属离子,这些金属离子对其功能有不可或缺的作用.理解金属蛋白质的作用.
