- n. An enzyme, α-D-glucosidase, which hydrolyzes maltose with production of glucose.
from The Century Dictionary and Cyclopedia
- n. 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.
Enzyme proteins catalyse reactions in the cytoplasm or outside the cell, such as maltase in the small intestine (more in digestion).
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).
This strain produces elevated levels of two enzymes, maltose permease and maltase, involved in starch degradation.
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.
The bill would add five lysosomol storage diseases to the newborn screening panel: Pompe disease or acid maltase deficiency; Krabbe disease or globoid cell leukodystrophy; Gaucher's disease; Niemann-Pick disease; and Fabry disease.
Pompe disease (glycogen storage disease type 2, acid maltase deficiency) is an enzyme deficiency with devastating effects - progressive muscle weakness and, in the severe infantile form, gross enlargement of the heart.
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.
The neurologist thought Tim was suffering from muscular dystrophy, but when a muscle biopsy came back it was clear that Tim had acid maltase deficiency, also known as Pompe disease.
Proset JPO for calling a spade a spade, we need to send them back at once and by the way Mr Neal Falzon need I remind you that when Malta was on the verge of a civil war, no foreign country raised a finger to our aid and it was the maltase alone that dwelt with the problem, accordingly WHY is it that we have to be the salvation of Africa?
There are three important disaccharidase enzymes: maltase maltose → glucose sucrase sucrose → glucose + fructose lactase lactose → glucose + galactose The disaccharidase enzymes are unusual in that they are located in the membrane of the ileum epithelial cells.
