Abstract
BIOSIS COPYRIGHT: BIOL ABS. 1. The optimal pH of sucrase was 5.8, which was slightly lower than the pH of the digestive gland. 2. The KM of sucrase was 0.184 M and the Vmax was 106.8 mumol/mg protein/hr. 3. The optimal temperature was 40?C and the activation energy was 10,600 cal/mol. 4. The most potent inhibitor of sucrase was mercury chloride, followed by copper sulphate, cadmium chloride, lead chloride and zinc chloride. 5. Starvation cause a decrease in the sucrase activity of the digestive gland.
