Abstract
Maltase (maltose glycohydrolase), isomaltase (isomaltose glycohydrolase), sucrase (sucrose glucohydrolase), palatinase (palatinose glucohydrolase), trehalase (trehalose glucohydrolase), lactae (lactose galactohydrolase) and cellobiae (cellobiose glucohydrolase) activities have been determined in the intestine of adult and suckling rats. All disaccharidase activities have been found to have the same distribution through the different sections of small intestine except for trehalose glucohydrolase activity which decreased distally more than the other disaccharides.
At birth lactose galactohydrolase and cellobiose glucohydrolase are very active, maltose glucohydrolase is low, and the other α-disaccharidases are absent. These activities appear on the 15th to 16th day after birth; at about the same time lactose galactohydrolase and cellobiose glucohydrolase activities are found to decrease.
