胃蛋白酶由胃粘膜主细胞分泌，分解食物中蛋白质成小肽段。一般用于神经性低酸症的鉴别，慢性胃炎、慢性胃扩张、慢性十二指肠炎等症状时也会引起胃蛋白酶分泌的减少。 测定原理：胃蛋白酶可催化血红蛋白水解，水解产物与福林试剂反应后显蓝色；一定范围内，其颜色的深浅与胃蛋白酶活性呈正比。
Gastric pepsin is secreted by the chief cells of the gastric mucosa and breaks down dietary proteins into small peptides. It is commonly used in the differential diagnosis of neurogenic hypoacidity. Conditions such as chronic gastritis, chronic gastric dilatation, and chronic duodenitis may also lead to reduced pepsin secretion. Determination Principle: Pepsin catalyzes the hydrolysis of hemoglobin, and the hydrolysis products react with Folin's reagent to produce a blue color. Within a certain range, the intensity of the color is proportional to pepsin activity.
