아미노산 중 alanine, threonine, isoleucine, leucine, aspartic acid, methionine, glutamic acid, tyrosine을 대상으로 열처리, 산처리, UV 광선 조사, 효소(trypsin)의 영향을 살펴보고 6N-HCl, <TEX>$105^{\circ}C$</TEX>로 가열했을 때 이성화하는 정도를 측정하였다. 또한 Mass Spectrometer를 이용할 때 각 아미노산의 fragment되는 과정을 조사하여 GC에서 서로 겹칠 때 분석하는 법을 개발하였다. HPLC에서 cyclodextrin bonded phase를 이용해서 dansyl amino acid의 분리를 시도하였다.
The importance of separation comes from demands on study for exact effect of synthetic drugs and the reactivity of enantiomer in biological system. Racemization rate was measured under the influence of heat, acid, UV-light, enzyme(trypsin) and 6N-HCl at <TEX>$105^{\circ}C$</TEX> on alanine, threonine, isoleucine, lecuine, aspartic acid, methionine, glutamic acid, tyrosine. The method for the identification of overlapped amino acids with GC was developed from the close study of fragmentation pattern with mass spectrometry. With cyclodextrin bonded phase by HPLC, the separation of dansyl amino acid was tested for compartison.
