Abstract
The heat inactivation of esterases in human and rabbit serum was followed at 50 and 55 degrees C by measuring the decrease of activity with paraoxon, phenylacetate and beta-naphthylacetate as substrates. The rate of inactivation measured with the three substrates was slightly, but significantly different, indicating that the substrates are hydrolysed by different enzymes.
摘要
通过以对氧磷、苯乙酸酯和β-萘乙酸酯为底物测量活性降低，在50℃和55℃下跟踪人血清和兔血清中酯酶的热失活情况。用这三种底物测得的失活速率略有不同，但差异显著，表明这些底物由不同的酶水解。
