The enzymes of some elasmobranchs from Bombay. IV. Lipases of Scoliodon sorrakowah and Rhyncobatus djddensis

Abstract

1. In S. sorrakowah and R. djddensis lipolytic activity is maximum in pancreas, minimum in spleen and kidney, intermediate in liver and absent in muscle and brain. 2. Aqueous glycerol and aqueous ethanol are good extractants of S. sorrakowah pancreatic lipase. 3. S. sorrakowah pancreatic lipase is obtained as a yellowish white powder. Activity of enzyme is a function of H⁺ concentration, time and enzyme concentration. Both CaCl₂ and bile salt are activators of the enzyme. Comparative rates of hydrolysis of different fats by enzyme have been studied.
