在260 ~ 340 ℃、30 MPa的恒压条件下，研究了甘氨酸的分解。主要产物为胺、有机酸和碳酸。基于这些产物，推测甘氨酸在水热条件下的分解采取两个主要途径，（即脱羧以产生氨和有机酸，以及脱氨基以产生碳酸和甲胺）。在实验条件范围内，甘氨酸的总分解速率与甘氨酸浓度呈一级关系。这些结果对于理解利用高温高压水从蛋白质生产氨基酸的行为具有重要的基础信息。
Decomposition of glycine was investigated in the temperature range of 260 to 340degreesC and at constant pressure of 30 MPa. Amines, organic and carbonic acids were obtained as major products. Based on these products, glycine decomposition under hydrothermal conditions is speculated to take two main paths, (i.e. decarboxylation to produce ammonia and organic acids, and deamination to produce carbonic acid and methylamine). The overall decomposition rate of glycine was found to be of the first order with respect to glycine concentration within the range of experimental conditions. These results are important as basic information in understanding the behavior of amino acid production from protein using high temperature and high pressure water.
