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

胰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.

而抗胰蛋白酶就是一种蛋白酶抑制剂，通过抑制胰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.

在当代，“正常”流感病毒需要在其人类宿主中有胰蛋白酶才能复制。

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

1918年的病毒甚至在没有胰蛋白酶的情况下也能增殖，这使得它比其他病毒更具致病性。

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

另外还有胰淀粉酶，可将碳水化合物分解为小分子的寡糖；再者还有蛋白酶，如胰蛋白酶，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.

于是胰蛋白酶原可能被转化为活化的胰蛋白酶，开启消化酶激活的级联反应，导致胰腺自溶——这就是急性胰腺炎。

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，这些酶原被释放入胰管，然后进入小肠，在那里它们被胰蛋白酶激活。

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.

你有胰蛋白酶和肽酶，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抗胰蛋白酶，释放入血进肺，在肺中像抑制胰蛋白酶一样，抑制中性粒细胞弹性蛋白酶，使弹性蛋白酶在水解弹性纤维之前失活。
