一：pepsin是什么意思（中英文）解释的意思

pepsin是一种消化酶，主要存在于胃液中，能够帮助分解蛋白质。它由胃腺细胞分泌，是胃液中最主要的消化酶之一。

Pepsin is a digestive enzyme that mainly exists in gastric juice and helps to break down proteins. It is secreted by gastric gland cells and is one of the main digestive enzymes in gastric juice.

二：怎么读（音标）

pepsin的音标为 /ˈpɛpsɪn/。

The pronunciation of pepsin is /ˈpɛpsɪn/.

三：用法

pepsin主要用于消化蛋白质，帮助人体吸收营养。它可以在胃液中起到重要的消化作用，将蛋白质分解成氨基酸，从而被人体吸收利用。

Pepsin is mainly used for digesting proteins and helping the body absorb nutrients. It plays an important role in gastric juice by breaking down proteins into amino acids for absorption by the body.

四：例句1-5句且中英对照

1. Pepsin is essential for proper digestion of proteins in the stomach.

胃液中的pepsin对于蛋白质的消化至关重要。

2. Pepsinogen, the inactive form of pepsin, is converted into pepsin by the acidic environment of the stomach.

胃液中的非活性pepsinogen会在胃酸的作用下转化为活性pepsin。

3. Pepsin works best in an acidic environment, which is why it is found in the stomach.

pepsin在酸性环境中效果最佳，这也是它存在于胃中的原因。

4. A deficiency in pepsin can lead to poor digestion and malnutrition.

缺乏pepsin可能会导致消化不良和营养不良。

5. The production of pepsin decreases as we age, making it harder for older adults to digest proteins.

随着年龄增长，人体产生的pepsin会减少，使得老年人更难消化蛋白质。

五：同义词及用法

1. 胃蛋白酶（gastric protease）：与pepsin具有相同的功能，也是胃液中的一种消化酶。

2. 蛋白酶（protease）：泛指一类能够分解蛋白质的酶，包括胰蛋白酶、肝蛋白酶等。

3. 消化酶（digestive enzyme）：指能够帮助分解食物、促进消化吸收的一类酶，包括淀粉酶、脂肪酶等。

1. Gastric protease: has the same function as pepsin and is also a digestive enzyme in gastric juice.

2. Protease: refers to a class of enzymes that can break down proteins, including pancreatic protease, liver protease, etc.

3. Digestive enzyme: refers to a class of enzymes that can help digest and absorb food, including amylase, lipase, etc.

六：编辑总结

pepsin是一种在胃液中起重要消化作用的消化酶，能够帮助分解蛋白质，促进人体吸收营养。它的主要用法是用于消化蛋白质，缺乏pepsin可能会导致消化不良和营养不良。同时，还有其他同义词如胃蛋白酶、蛋白酶和消化酶等。了解pepsin的功能和用法可以帮助我们更好地维护胃部健康，保证身体正常的消化吸收功能。
