Description
Alpha-glucosidase is a glucosidase located in the brush border of the small intestine that acts upon 1,4-alpha bonds. This is in contrast to beta-glucosidase. Alpha-glucosidase breaks down starch and disaccharides to glucose. Maltase, a similar enzyme that cleaves maltose, is nearly functionally equivalent.
Product Overview
The enzyme catalyses the hydrolyzis of a-1.6 linked a-galactose residues from oligosaccharides
Enzyme Commission Number
EC 3.2.1.20
Unit Definition
One unit (U) is defined as the amount of enzyme which liberates 1 μmol of p-nitrophenol per min from pNP-α-galactoside, under the given assay conditions.
