1. The rates of heat inactivation of papain, bromelin, and asclepain were determined at several different temperatures. Papain was by far the most resistant to heat. 2. The destruction of papain at 75-83 degrees and bromelin at 55-70 degrees followed the course of a first order reaction, except that for longer times of heating, bromelin (at 60-70 degrees ) was inactivated more rapidly than the first order equation required. 3. The rate of inactivation of asclepain at 55-70 degrees followed the second order equation. 4. The critical thermal increments of inactivation of papain and bromelin, calculated with the van't Hoff-Arrhenius equation, were of the same high order that has been found for protein denaturation. The increment for asclepain was somewhat lower.
