多酶片又称三酶片,其组成是胃蛋白酶、淀粉酶和胰酶。这三种酶中,胃蛋白酶消化蛋白质的最适宜pH 值是1.5～2.5,在碱性溶液中易被破坏失效,在酸性溶液中较稳定。胰酶消化蛋白质的最适宜 pH 值是8.4,在酸性介质中胰酶要被胃蛋白酶消化,因此在内服时需包上肠溶衣或制成肠溶胶丸,或与碳酸氢钠在饭时服用。淀粉酶分解淀粉时最适宜的 pH 值为6.8。可见三种酶所需的 pH 值不同,产生作用的条件
Multi-enzyme tablets, also known as three enzyme tablets, its composition is pepsin, amylase and pancreatin. Of these three enzymes, the optimum pH for pepsin digestion of protein is 1.5-2.5, which is easily destroyed in alkaline solution and more stable in acidic solution. Trypsin digestion of protein optimum pH value is 8.4, trypsin in acidic medium to be digested by pepsin, so when the need to package on the enteric coating or enteric coated pellets, or with sodium bicarbonate in the meal. The most suitable pH for amylase to decompose starch is 6.8. Visible three enzymes required for different pH, the role of the conditions
