mal·tase (mawlґtās) 1. α-glucosidase. 2. any enzyme with similar glycolytic activity, cleaving α-1,4 or sometimes α-1,6 linked glucose residues from nonreducing termini; in humans there are considered to be four such enzymes. Two are the heat-stable enzymes usually called maltases, constituting the glucoamylase complex (q.v.); the other two are the heat-labile enzymes more commonly called sucrase and α-dextrinase that constitute the sucrase-isomaltase complex (q.v.).Medical dictionary. 2011.
