Amylase catalyzes a reaction with starch to directly create _______.
mario62 [17]

Maltose is produced instantly when amylase reacts with starch.

Starch is a polysaccharide molecule made of glucose units. The chemical formula of the starch is written as (C₆H₁₀O₅)ₙ. The starch consists of amylose and amylopectin. The glucose units in this starch are linked with the help of two kinds of bonds α 1,4 glycosidic linkages and α 1,6 glycosidic linkages.

This starch molecule is first hydrolyzed into shorter polysaccharides, dextrins, and maltose with a help of an enzyme called amylase. The maltose can be further hydrolyzed into glucose units with the help of the maltase enzyme.

Therefore, the blank can be filled with maltose.
