Reaction: Digestion of 1-6 linkages of limit dextrins to yield maltose, maltotriose, longer maltosides, and glucose
- in pathway: Digestion of dietary carbohydrate
The 1-6 linkages in extracellular limit dextrins are hydrolyzed by sucrase-isomaltase to yield maltose, maltotriose, longer maltosides, and glucose (Conklin et al. 1975; Nichols et al. 1998). In the body, this enzyme is found on the external face of enterocytes in microvilli of the small intestine (Hauri et al. 1985), and acts on limit dextrins generated by the hydrolysis of amylopectin starch.
