Methionine is the rare amino acid that contains sulfur, an element known for its pungent odor.

甲硫氨酸是一种稀有氨基酸含有硫，一种含有刺激元素。

In severe cases, the inability to process methionine can lead to neurological problems and muscle weakness, among other problems in the nervous system.

在严重例子中，处理甲硫氨酸无能会导致神障碍肌无力和其他神系统问题。

Sometimes the condition comes about just because you've eaten too much methionine, which is in protein-rich foods, like meat and cheese.

所以产生体就是你吃了太多甲硫氨酸，存在于高蛋白食物中，比如肉和奶酪。

Again, treatment usually involves avoiding foods that contain methionine, as well as taking supplements to make sure that the body is getting what it needs.

同样治疗方法通常包括避免含有甲硫氨酸食物，同时吃一些能保证身体需要营养品。

But if the cause is genetic, it can be due to mutations in one of several genes that are responsible for making the enzymes that help break down methionine.

但是如果起是基，可以被归咎于一些能够生成酶促使分解甲硫氨酸基突变。
