| 描述 Description |
胃蛋白酶是一种消化酶;它是在PH值1.5-5.0下从胃蛋白酶原中提取的，胃蛋白酶原由胃细胞分泌。胃蛋白酶在胃酸的作用下可将固化的蛋白质分解为蛋白胨，但不能进一步分解为氨基酸。胃蛋白酶的最佳有效条件为PH值为1.6 ~ 1.8。 Pepsin is a digestive enzyme; it is extracted from Pepsinogen under PH 1.5-5.0 and the pepsinogen is secreted by the stomach cell.Pepsin can decompose the solidified proteins into peptone by effect of stomach acid, but it can not go any further to amino acid. The best effective condition for pepsin is PH 1.6-1.8. |

| 功能 Functions |
1. 胃蛋白酶可以用作消化药物。常用于因食用蛋白质过多而引起的食物消化不良、消化功能疾病的恢复以及慢性萎缩性胃炎、胃癌、恶性白血病等引起的胃蛋白酶缺乏症等症状。 Pepsin can be used as a digestive drug. Commonly used due to excessive consumption of protein foods caused by indigestion, recovery of the disease after the digestive function and chronic atrophic gastritis, gastric cancer, pernicious leukemia caused by pepsin deficiency and other symptoms. 2. 酶制剂。主要用于制作鱼粉和其他蛋白质(如大豆蛋白)的水解，制作奶酪中的凝乳效果(结合胆红素)，还可用于防止啤酒凝固和浑浊。 Enzyme preparation. Mainly used for the manufacture of fishmeal and other proteins (such as soy protein) hydrolysis, cheese in the manufacture of curd effect (in combination with the bilirubin), can also be used to prevent beer frozen and turbid. 3.用于生化研究、蛋白质结构分析、消化酶医药等。 For biochemical research, protein structure analysis, medicine used as digestive enzymes. 4. 帮助消化的药物，用于胃蛋白酶缺乏或因消化不良疾病引起的消化功能障碍。 To help digestive drugs, for the lack of pepsin or digestive dysfunction after the disease caused by indigestion. 5. 此外，在牛奶的制造过程中，当用作干燥胃的替代品时要冷却。 In addition, in the manufacture of milk cool when used as a substitute for dry stomach |
