|succinic dehydrogenase;琥珀酸脱氢酶
琥珀酸脱氢酶（Succinate Dehydrogenase，简称SDH）是一种存在于线粒体内膜上的关键酶复合物，在细胞能量代谢中扮演双重角色：
三羧酸循环（TCA循环）的组成部分
它催化琥珀酸（succinate）氧化脱氢生成延胡索酸（fumarate）。这是TCA循环的第六步反应，释放的氢原子（以2H⁺和2e⁻形式）进入后续电子传递链：
$$ce{ Succinate + FAD -> Fumarate + FADH2 }$$
电子传递链（呼吸链）的复合体II
作为复合体II（Complex II），它将上述反应中产生的电子从FADH₂传递至辅酶Q（泛醌），最终驱动质子泵产生ATP。其电子传递路径为：
$$ce{ FADH2 -> Iron-sulfur clusters -> Coenzyme Q }$$
结构特征：
SDH是由4个亚基组成的膜蛋白复合物：
