芳香化酶、芳香酶（EC 1.14.14.14、英语：Aromatase），也称为雌激素合成酶（英语：estrogen synthetase）或雌激素合酶（英语：estrogen synthase），是一种单加氧酶，负责雌激素生物合成的关键步骤。由人体基因CYP19A1编码，是CYP450 酶蛋白质超家族成员，可催化类固醇生成涉及的许多反应。催化涉及甾体激素合成步骤中从雄激素到雌激素的芳香化（英语：Aromatization）反应。芳香化酶在许多人体组织中出现，如生殖腺（颗粒细胞（英语：granulosa cell））、脑、脂肪组织、胎盘、血管、皮肤和骨骼，对青春期的第二性征发育有重要作用。

催化机理

雄烯二酮 + 3O₂ + 3NADPH + 3H⁺

\rightleftharpoons

雌酮 + Formate + 4H₂O + 3NADP⁺

睾酮 + 3O₂ + 3NADPH + 3H⁺

\rightleftharpoons

雌二醇 + Formate + 4H₂O + 3NADP⁺

芳香酶催化的睾酮转化到雌二醇的反应。类固醇由四个稠合的环（标记为A到D）组成。芳香酶将标记为A环芳香化

芳香化酶的催化机理：雄烯二酮转化为雌酮的芳香酶催化机理。雄激素的19-甲基基团经过连续三次羟基化和脱水后，再以甲酸形式消去，同时A环发生芳香化^[7]
