Abstract
Proteins in papillae on the bovine tongue were analyzed by semi-micro, polyacrylamide gel electrophoresis. All the proteins in the papillae with taste buds were observed to be common to proteins in the surrounding epithelium without taste buds. The protein band which was reported to form a weak complex with compounds called sweet by man was also found in all parts of the tongue epithelium. The receptor molecules for chemical stimuli may be distributed in all the cells of the tongue epithelium or the content of receptor molecules in taste bud papillae may be extremely low.
摘要
通过半微量聚丙烯酰胺凝胶电泳分析了牛舌乳头中的蛋白质。观察到有味蕾的乳头中的所有蛋白质与周围无味蕾的上皮中的蛋白质相同。据报道与被人类称为甜味的化合物形成弱复合物的蛋白带也在舌上皮的所有部位被发现。化学刺激的受体分子可能分布在舌上皮的所有细胞中，或者味蕾乳头中受体分子的含量可能极低。
