WebOligo-1,6-glucosidase (EC 3.2.1.10, sucrase-isomaltase, SI; systematic name oligosaccharide 6-α-glucohydrolase) is a glucosidase enzyme located on the brush border of the small intestine, which catalyses the following reaction: WebDisaccharidase. Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides. In the human body, disaccharidases are made mostly in an area of the small intestine 's wall called the brush border, making them members of the group of "brush border enzymes".
