Abstract
The heat inactivation of esterases in human and rabbit serum was follo wed at 50 and 55-degrees-C by measuring the decrease of activity with paraoxon, phenylacetate and beta-naphthylacetate as substrates. The ra te of inactivation measured with the three substrates was slightly, bu t significantly different, indicating that the substrates are hydrolys ed by different enzymes.
