?一：pepsin是什么意思（中英文）解釋的意思

pepsin是一種消化酶，主要存在于胃液中，能夠幫助分解蛋白質(zhì)。它由胃腺細(xì)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：怎么讀（音標(biāo)）

pepsin的音標(biāo)為 /?p?ps?n/。

The pronunciation of pepsin is /?p?ps?n/.

三：用法

pepsin主要用于消化蛋白質(zhì)，幫助人體吸收營(yíng)養(yǎng)。它可以在胃液中起到重要的消化作用，將蛋白質(zhì)分解成氨基酸，從而被人體吸收利用。

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句且中英對(duì)照

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

胃液中的pepsin對(duì)于蛋白質(zhì)的消化至關(guān)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會(huì)在胃酸的作用下轉(zhuǎn)化為活性pepsin。

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

pepsin在酸性環(huán)境中效果最佳，這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可能會(huì)導(dǎo)致消化不良和營(yíng)養(yǎng)不良。

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

隨著年齡增長(zhǎng)，人體產(chǎn)生的pepsin會(huì)減少，使得老年人更難消化蛋白質(zhì)。

五：同義詞及用法

1. 胃蛋白酶（gastric protease）：與pepsin具有相同的功能，也是胃液中的一種消化酶。

2. 蛋白酶（protease）：泛指一類能夠分解蛋白質(zhì)的酶，包括胰蛋白酶、肝蛋白酶等。

3. 消化酶（digestive enzyme）：指能夠幫助分解食物、促進(jìn)消化吸收的一類酶，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：編輯總結(jié)

pepsin是一種在胃液中起重要消化作用的消化酶，能夠幫助分解蛋白質(zhì)，促進(jìn)人體吸收營(yíng)養(yǎng)。它的主要用法是用于消化蛋白質(zhì)，缺乏pepsin可能會(huì)導(dǎo)致消化不良和營(yíng)養(yǎng)不良。同時(shí)，還有其他同義詞如胃蛋白酶、蛋白酶和消化酶等。了解pepsin的功能和用法可以幫助我們更好地維護(hù)胃部健康，保證身體正常的消化吸收功能。
