Abstract
A high content of methionine sulfoxide was observed in the resiliums (internal hingeligaments) of surf clams. As no isolation procedure which might cause the oxidation of methionine to methionine sulfoxide was involved and the hydrolysis was carried out in vacuo, it is the first solid evidence for the presence of methionine sulfoxide as a constituent of natural protein.
摘要
在 surf 蛤的 resiliums（内部铰合韧带）中观察到高含量的甲硫氨酸亚砜。由于未涉及任何可能导致甲硫氨酸氧化为甲硫氨酸亚砜的分离程序，且水解是在真空中进行的，这是甲硫氨酸亚砜作为天然蛋白质成分存在的首个确凿证据。
