英英释义

Methemoglobin (British English: methaemoglobin) (pronounced \"met-hemoglobin\") is a form of the oxygen-carrying metalloprotein hemoglobin, in which the iron in the heme group is in the Fe3+ (ferric) state, not the Fe2+ (ferrous) of normal hemoglobin. Methemoglobin cannot bind oxygen, unlike oxyhemoglobin.

双语例句

用作名词(n.)Enzymes are also important in preventing hemoglobin from being oxidized to methemoglobin, which cannot carry oxygen.酶对防止血红蛋白氧化成不能携带氧气的高铁血红蛋白是很重要的。The formation of methemoglobin reduces the amount of oxygen available to body tissues.高铁血红蛋白的形成减少了身体组织可以得到的氧的数量。
