Digestive carbohydrate-hydrolyzing enzymes

Digestive carbohydrate-hydrolyzing enzymes, primarily alpha-amylase and alpha-glucosidase, are essential proteins responsible for the breakdown of complex dietary carbohydrates into absorbable monosaccharides like glucose [1, 2]. Alpha-amylase, secreted by the salivary glands and pancreas, initiates the process by hydrolyzing starch into smaller oligosaccharides, while alpha-glucosidases (such as maltase, sucrase, and glucoamylase) located in the brush border of the small intestine complete the conversion to glucose [2, 4]. These enzymes are key therapeutic targets in the management of type 2 diabetes mellitus and obesity [1, 3]. By inhibiting their activity, drugs like acarbose and miglitol delay carbohydrate digestion and slow the absorption of glucose into the bloodstream, effectively reducing postprandial blood sugar spikes [1, 5]. However, the presence of undigested carbohydrates in the colon can lead to fermentation by gut microbiota, resulting in common gastrointestinal side effects such as flatulence, bloating, and diarrhea [1, 3]. Clinical monitoring typically involves measuring postprandial glucose levels and glycated hemoglobin to assess efficacy [1, 5].

Competitive inhibition of alpha-amylase and alpha-glucosidase enzymes in the gastrointestinal tract, which delays the hydrolysis of complex carbohydrates and disaccharides into absorbable monosaccharides, thereby slowing glucose absorption and reducing postprandial blood glucose excursions.
