And then I would take bromantain to upregulate tyrosine hydroxylase.

然后我会抗胺来上调氨酸羟化酶。

First, with the help of enzyme tyrosine hydroxylase (TH), tyrosine gets converted to L-dopa, also known as levodopa.

首先，在氨酸羟化酶（TH）的帮助下，氨酸也转化为左旋多巴被称为左旋多巴。

Medications like phenytoin, an anticonvulsant, uses liver and kidney hydroxylase enzymes for its own metabolism, so especially with long term use, there's not enough vitamin D being generated.

苯妥英，一种抗惊厥药物，会肾的羟化酶于药物代谢，所以对于尤其是长期该药的患者，其维生素D生成可能不足。
