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

胰是一类，能够水解多种质。

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的情况下也能，使得它比其他病毒更具致病性。

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才能复制。

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，可将碳水化合物分解为小分子的寡糖；再者还有，如胰，可将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.

于是胰原可能被转化为活化的胰，开启消化激活的级联反应，导致胰腺自溶——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，些原被释放入胰管，然后进入小肠，在那里它们被胰激活。

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，释放入血进肺，在肺中像抑制胰一样，抑制中性粒细胞弹性，使弹性在水解弹性纤维之前失活。
