芳香化酶（英語：Aromatase）也被称为雌激素合成酶（estrogen synthetase）是雌激素生物合成的关键酶，在人体内由基因 CYP19A1 编码，是细胞色素P450超家族的一员，EC 1.14.14.1。芳香化酶是一种单加氧酶，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、脂肪組織、胎盤、血管、皮膚和骨骼，对青春期的第二性征发育有重要作用。

由芳香化酶催化的从睾酮到雌二醇的反应甾体激素四个环（A环到D环）中的A环发生芳香化

催化机理编辑

芳香化酶的催化机理：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]
