摘　　要：考查了金属离子、葡萄糖、蔗糖、甘油、表面活性剂对蛋白酶在羊毛减量率及有关方面的影响。它们在一定条件下能提高蛋白酶对羊毛的减量率,但原因却不同。金属离子的作用主要是提高蛋白酶的活力,葡萄糖、蔗糖、甘油主要是维持蛋白酶在水溶液中高级结构的稳定性,而表面活性剂能降低溶液表面自由能,降低蛋白酶从溶液扩散到羊毛纤维表面的能垒。In this paper, effect of chemicals on wool hydrolysis by protease was studied. These chemicals are metal ions, glucose, sucrose, glycerol, and surface-activated agents. On proper conditions, they can improve the ability of protease to hydrolyze wool, but the mechanism is different. The function of metal ions is to increase protease activity; glucose,surose and glycerol can keep the stability of the high grade structure of protease in solution. Surface-activated agents can low the surface free energy of the solution and reduce the hindrance met by protease when it diffuses to the surface of wool fiber.
