These enzymes include peptidase, sucrase, maltase, lactase and intestinal lipase. Other examples include lactase, amylase, chitinase, sucrase, maltase, neuraminidase, invertase, hyaluronidase and lysozyme. Additional digestive enzymes produced by these glands include dipeptidases, maltase, sucrase, lactase, and enterokinase. Furthermore, for the cleavage of disaccharides, there are maltase, lactase, sucrase, trehalase and others. Invertase is a sucrase used industrially for the hydrolysis of sucrose to so-called invert sugar. To test for sucrose, the sample is treated with sucrase. If the enzyme sucrase is added, however, the reaction will proceed rapidly. Sucrase-isomaltase consists of two enzymatic subunits&colon; sucrase and isomaltase.
