Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides.In the human body, disaccharidases are made mostly in an area of the small intestine's wall called the brush border, making them members of the group of "brush border enzymes".
Excessive flatus and abdominal bloating may reflect excessive gas production due to fermentation of unabsorbed carbohydrate, especially among patients with a primary or secondary disaccharidase deficiency, such as lactose intolerance or sucrose intolerance. Malabsorption of dietary nutrients and excessive fluid secretion by inflamed small ...
Sucrose intolerance can also be caused by irritable bowel syndrome, aging, or small intestine disease (secondary sucrose intolerance). There are specific tests used to help determine if a person has sucrose intolerance. The most accurate test is the enzyme activity determination, which is done by biopsying the small intestine.
271.2 Hereditary fructose intolerance; 271.3 Intestinal disaccharidase deficiencies and disaccharide malabsorption. Lactose intolerance; Glucose intolerance; 271.4 Renal glycosuria; 271.8 Other specified disorders of carbohydrate transport and metabolism; 271.9 Unspecified disorder of carbohydrate transport and metabolism
With sucrose intolerance, the result of consuming sucrose is excess gas production and often diarrhea and malabsorption. Lactose intolerance is a similar condition that reflects an individual's inability to hydrolyze the disaccharide lactose. Sucrase is secreted by the tips of the villi of the epithelium in the small intestine.
Various functional consequences of bacterial infiltration cause enterocyte damage in the jejunum such as diminished disaccharidase activity, fat malabsorption, decreased amino acid transport and decreased vitamin B 12 absorption. Thus, detection of proximal bacterial overgrowth is critical.
A 2018 review concluded that although fructan intolerance may play a role in non-celiac gluten sensitivity, it only explains some gastrointestinal symptoms. Fructan intolerance does not explain the extra-digestive symptoms that people with non-celiac gluten sensitivity may develop, such as neurological disorders , fibromyalgia , psychological ...
Breaking apart a double sugar into its two monosaccharides is accomplished by hydrolysis with the help of a type of enzyme called a disaccharidase. As building the larger sugar ejects a water molecule, breaking it down consumes a water molecule. These reactions are vital in metabolism.
