is an enzyme that breaks down the disaccharide
A disaccharide or biose is the carbohydrate formed when two monosaccharides undergo a condensation reaction which involves the elimination of a small molecule, such as water, from the functional groups only. Like monosaccharides, disaccharides form an aqueous solution when dissolved in water...
Maltose , or malt sugar, is a disaccharide formed from two units of glucose joined with an αbond, formed from a condensation reaction. The isomer "isomaltose" has two glucose molecules linked through an α bond. Maltose is the second member of an important biochemical series of glucose chains....
. Maltase is an enzyme that catalyzes the hydrolysis of the disaccharide maltose to the simple sugar glucose. This enzyme is found in plants, bacteria, and yeast. Then there is what is called Acid maltase deficiency. It is categorized into three separate types based on the age of onset of symptoms in the affected individual.
In most cases, it is equivalent to alpha-glucosidase
Alpha-glucosidase is a glucosidase acting upon 1,4-alpha bonds. This is in contrast to beta-glucosidase.The term maltase, which refers to an enzyme cleaving maltose, is nearly equivalent.Types include:* Acid alpha-glucosidase* neutral** GANAB** GANC...
, but the term "maltase" emphasizes the disaccharide nature of the substrate from which glucose
Glucose is a simple sugar and an important carbohydrate in biology. Cells use it as the primary source of energy and a metabolic intermediate...
is cleaved, and "alpha-glucosidase" emphasizes the bond, whether the substrate is a disaccharide or polysaccharide
Polysaccharides are long carbohydrate molecules, of repeated monomer units joined together by glycosidic bonds. They range in structure from linear to highly branched. Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure,...
