the reversible dehydration of pyruvate hydrate were studied at 25.0 o C using spectrophotometric methods. The enolization of pyruvate was followed at 353 nm by monitoring the rate of uptake of triiodide ion. The dehydration of pyruvate hydrate was initiated by introducing small quantities of preacidified solutions of pyruvicacid containing, at the kinetic zero, ca. 60% of the hydrate into buffer solutions
使用分光光度法在 25.0 o C 下研究了丙酮酸的烯醇化和丙酮酸水合物的可逆脱水。通过监测三碘化物离子的吸收速率,在 353 nm 处跟踪丙酮酸的烯醇化。丙酮酸水合物的脱水是通过引入少量的丙酮酸预酸化溶液引发的,在动力学为零时,大约为 60%的水合物变成缓冲溶液。随着反应进行到最终溶液组成为 6% 水合物,325 nm 处的吸光度下降
