Sucrase - Wikipedia Sucrase Sucrase is a digestive enzyme secreted in the small intestine. Sucrase enzymes are located on the brush border of the small intestine. The enzymes catalyze the hydrolysis of sucrose to fructose and glucose. The sucrase enzyme invertase, which occurs more commonly in plants, also hydrolyzes sucrose but by a different mechanism.

With sucrose intolerance, the result of consuming sucrose is excess gas production and often diarrhea and malabsorption. Lactose intolerance is a related disorder 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. Its levels are reduced in response to villi - blunting events such as celiac sprue and the inflammation associated with the disorder. The levels increase in pregnancy, lactation, and diabetes as the villi hypertrophy. Use in chemical analysis Sucrose is a non-reducing sugar, so will not test positive with Benedict 's solution. To test for sucrose, the sample is treated with sucrase. The sucrose is hydrolysed into glucose and fructose, with glucose being a reducing sugar, which in turn tests positive with Benedict 's solution.. References Jump up ^ Tortora, Gerard ( 2014 ).
