Discovery of diastase
Today, "diastase" refers to any α-, β-, or γ-amylase (all of which are hydrolases) that can break down carbohydrates. The commonly used -ase suffix for naming enzymes was derived from the name diastase. When used as a pharmaceutical drug, diastase has the ATC code A09AA01 . See more A diastase is any one of a group of enzymes that catalyses the breakdown of starch into maltose. For example, the diastase α-Amylase degrades starch to a mixture of the disaccharide maltose; the trisaccharide … See more • Takadiastase • Whipple disease • amylase See more Urine diastase is useful in diagnosing uncertain abdominal cases (especially when pancreatitis is suspected), stones in the common bile duct (choledocholithiasis), jaundice and … See more • Diastase at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • Introduction and Uses of Diastase Enzyme See more Webdiastase: [ di´ah-stās ] a combination of enzymes produced during germination of seeds, and contained in malt; it converts starch into maltose and then into glucose.
