  • noun An enzyme that catalyzes the hydrolysis of maltose to glucose.

from The Century Dictionary.

  • noun A ferment which causes the cleavage of maltose into two molecules of dextrose. Maltase, like lipase, has been shown to be capable of reversible action in concentrated solutions. It occurs widely distributed in both the animal and the vegetable world.

  • Some well-understood examples of these sorts of mutations include the single base pair changes that lead to cystic fibrosis, sickle cell anemia or other, rarer hereditary diseases like familial dysautonomia or acid maltase disease (a.k.a. Glycogen storage disease type II or Pompe disease, as was featured in recent Harrison Ford flick Extraordinary Measures).

  • The starch in the grain is typically broken down to component sugars, first by a process of malting in which the grain is soaked in water to germinate so that the enzyme maltase is produced and the starch broken down to the disaccharide maltose.

  • That's because people with Pompe disease, also called acid maltase deficiency, don't produce an enzyme that breaks down glycogen, a sugar stored in the body's muscle cells.
