消旋丙氨酸鎳四水合物(Ni(CH_3CH(NH_2)COO)_2-4H_2O)晶體結構的研究工作,是本文作者之一(盧嘉錫)在美国加州理工学院研究晶體結構時在L.Pauling教授的直接领导和A.J.Stosick博士的協助下开始的,當時該校Pauling学派正展开氨酸和蛋白质結構化學的系統研究,希望通過這个研究计划能够找出较简单的生命质的內部结构,來了解這些物质中分子内部和分子间作用力,因此一方面直接探討較簡单氨酸(已完成發表的,截至1954年止,計有环二縮弍乙氨酸((NHCH_2CO)_2)、乙氨酸(NH_2CH_2COOH)、消旋丙氨酸(CH_3CH(NH_2)COOH)、β-乙氨醯乙氢酸(NH_2CH_2CONHCH_2COOH)、乙醯乙氨酸(CH_3CONHCH_2COOH)、左旋3-羟基2丁氨酸(CH_3CH(OH)CH(NH_2)COOH、羟基左旋氮伍圈氨酸(C_4H_9N(OH)COOH)、
The study of the crystal structure of racemic alanine nickel tetrahydrate (Ni (CH 3 CH (NH 2) COO) _2-4H 2 O) is one of the authors (Lu Jiaxi) studied the crystal structure of the California Institute of Technology in the United States when Professor L. Pauling With direct help from Dr. AJ Stosick, when the school’s Pauling School was conducting a systematic study of the structural chemistry of proteins and proteins in the hope of finding a simpler internal structure of life through this research project Therefore, on the one hand, the simpler amino acids are directly discussed (published, as of 1954, there are two kinds of ring ammonia ((NHCH2CO) 2), ammonia (NH_2CH_2COOH), racemic alanine (CH_3CH (NH_2) COOH), β-ethylamine 醯 HCH_2COOH, CH_3CONHCH_2COOH, OH) CH (NH 2) COOH, hydroxyl levamlocin (C_4H_9N (OH) COOH),
