실험 절차

When applied to an amino acid analyzer and a paper chromatography, the isolated substance exhibited the same behavior as a standard substance of theanine. Furthermore, hydrolysis of the isolated substance using hydrochloric acid or glutaminase yielded L-glutamine and ethylamine at a ratio of 1:1. Thus, since hydrolysis of the isolated substance by glutaminase was thus possible, ethylamine was proved to be combined with the gamma-position of L-glutamine. Furthermore, it was confirmed by L-glutamic acid dehydrogenaze (GluDH) that glutamine yielded by hydrolysis was of L-type. FIG. 4 shows infrared absorption spectrometry (IR) spectra of theanine sample and isolated substance. Both substances exhibited spectra similar to each other. Consequently, the isolated substance was proved to be theanine.
