Trypsins are a type of protease, which is an enzyme that can break down other proteins.

蛋白酶是一类蛋白酶，能够水解多种蛋白质。

So this antitrypsin protein is a protease inhibitor, and inactivates trypsins, thereby preventing protein breakdown.

而抗蛋白酶就是一种蛋白酶抑制剂，通过抑制蛋白酶防止蛋白质水解。

Contemporary, 'normal' flu viruses require the presence of the enzyme trypsin in their human host, in order to replicate.

当代，“正常”流感病需要其人类宿主中有蛋白酶才能复制。

The 1918 virus instead could proliferate even in the absence of trypsin, making it more pathogenic than other viruses.

1918年的病没有蛋白酶的情况下也能增殖，这使得它比其他病更具致病性。

There's also pancreatic amylase which breaks down carbohydrates into shorter oligosaccharides, and proteases, like trypsin, which cleaves proteins down into smaller peptides.

另外还有淀粉酶，可将碳水化合物分解为小分子的寡糖；再者还有蛋白酶，如蛋白酶，可将蛋白质分解成小分子肽链。

Trypsinogen might then be turned into activated trypsin which begins the cascade of digestive enzyme activation and autodigestion of the pancreas—which is acute pancreatitis.

于是蛋白酶原可能被转化为活化的蛋白酶，开启消化酶激活的级联反应，导致腺自溶——这就是急性腺炎。

To digest a meal, these zymogens are released into the pancreatic duct, and delivered to the small intestine where they are activated by the protease trypsin.

当消化食物时，这些酶原被释放入管，然后进入小肠，那里它们被蛋白酶激活。

You've got trypsin and peptidase in there, which break proteins down into amino acids, and you have lipases that turn triglycerides into fatty acids and glycerol.

你有蛋白酶和肽酶，它们将蛋白质分解成氨基酸，还有脂肪酶将甘油三酯转化为脂肪酸和甘油。

Fortunately, the liver makes alpha-1 antitrypsin which gets released into the blood and sent to the lungs, where it inhibits neutrophil elastase just like it inhibits trypsin, inactivating it before it can break down the protein elastin.

幸运的是，肝产生α-1抗蛋白酶，释放入血进肺，肺中像抑制蛋白酶一样，抑制中性粒细胞弹性蛋白酶，使弹性蛋白酶水解弹性纤维之前失活。
