Four subjects were given test meals containing various concentrations of hydrochlorides of glycine, alanine, arginine, phenylalanine and tryptophan. The gastric contents were recovered after 20 min. The volume of the original meal recovered was assessed from the amount of marker substance aspirated. It was found that the slowing of gastric emptying of amino acid hydrochlorides was consistent with their action as weak acids. However, tryptophan and phenylalanine were slightly more effective than was predicted on the basis of their actions as acids.
给4名受试者提供了含有不同浓度甘氨酸、丙氨酸、精氨酸、苯丙氨酸和色氨酸盐酸盐的试验餐。20分钟后收集胃内容物。根据吸出的标记物质的量评估回收的原始餐食的体积。发现氨基酸盐酸盐胃排空减慢与其作为弱酸的作用一致。然而，色氨酸和苯丙氨酸的作用比基于其作为酸的作用所预测的略强。
