胃蛋白酶是蛋白质类物质,它的溶液具有胶体性质。胃蛋白酶合剂的一般配制方法是把胃蛋白酶的干粉撒在酸性溶剂的表面,与水接触的胃蛋白酶先吸水膨脹而溶解,生成的胶体溶液由于比重較大而下沉,让新的溶剂来继续溶解胃蛋白酶,如此反复一直到全部干粉都溶 Pepsin is a proteinaceous substance whose solution has colloidal properties. The general preparation method of pepsin mixture is to pepsin dry powder sprinkled on the surface of acidic solvent, pepsin contact with water first water swelling and dissolution, the resulting colloidal solution due to the larger proportion and sink, let the new solvent to continue Dissolved pepsin, so repeatedly until all the dry powder is dissolved
