Abstract
- Results of laboratory experiments which compared horse and human serum butyrylcholinesterase (EC 3.1.1.8) with respect to their acid inactivation and ammonium sulfate protection show: 2. Horse serum butyrylcholinesterase is more resistant to inactivation at pH 3.0 than human serum butyrylcholinesterase. 3. The loss of activity at pH 3.0 for both horse and human butyrylcholinesterase does not follow first order kinetics. 4. Both human and horse serum butyrylcholinesterase are protected from pH 3.0 inactivation by ammonium sulfate concentrations up to 33% saturation (1.37 M).
摘要
- 比较马血清和人血清丁酰胆碱酯酶（EC 3.1.1.8）的酸灭活和硫酸铵保护作用的实验室实验结果表明：2. 马血清丁酰胆碱酯酶在pH 3.0时比人血清丁酰胆碱酯酶更耐灭活。3. 马和人丁酰胆碱酯酶在pH 3.0时的活性丧失不遵循一级动力学。4. 高达33%饱和度（1.37 M）的硫酸铵浓度可保护人血清和马血清丁酰胆碱酯酶不被pH 3.0灭活。
