English-Chinese/During human digestion

During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions. This is crucial for the absorption of the essential amino acids that cannot be biosynthesized by the body.

在人类消化过程中，蛋白质通过盐酸和蛋白酶作用在胃中分解成较小的多肽链. 这对于吸收不能被身体生物合成的必需氨基酸至关重要.
