| 描述 Description |
胃蛋白酶是一種消化酶;它是在PH值1.5-5.0下從胃蛋白酶原中提取的，胃蛋白酶原由胃細(xì)胞分泌。胃蛋白酶在胃酸的作用下可將固化的蛋白質(zhì)分解為蛋白胨，但不能進(jìn)一步分解為氨基酸。胃蛋白酶的最佳有效條件為PH值為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藥物。常用于因食用蛋白質(zhì)過多而引起的食物消化不良、消化功能疾病的恢復(fù)以及慢性萎縮性胃炎、胃癌、惡性白血病等引起的胃蛋白酶缺乏癥等癥狀。 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. 酶制劑。主要用于制作魚粉和其他蛋白質(zhì)(如大豆蛋白)的水解，制作奶酪中的凝乳效果(結(jié)合膽紅素)，還可用于防止啤酒凝固和渾濁。 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、蛋白質(zhì)結(jié)構(gòu)分析、消化酶醫(yī)藥等。 For biochemical research, protein structure analysis, medicine used as digestive enzymes. 4. 幫助消化的藥物，用于胃蛋白酶缺乏或因消化不良疾病引起的消化功能障礙。 To help digestive drugs, for the lack of pepsin or digestive dysfunction after the disease caused by indigestion. 5. 此外，在牛奶的制造過程中，當(dāng)用作干燥胃的替代品時(shí)要冷卻。 In addition, in the manufacture of milk cool when used as a substitute for dry stomach |
