Dextrin catabolic process refers to the breakdown of dextrins, which are linear chains of glucose units linked by α-1,4-glycosidic bonds. This process is a crucial step in the digestion of carbohydrates, specifically starch, and is primarily carried out by enzymes known as dextrinases. Dextrins are produced by the initial breakdown of starch by salivary and pancreatic α-amylases.

The process begins with the hydrolysis of α-1,4-glycosidic bonds within the dextrin chains, catalyzed by dextrinases. These enzymes, such as isomaltase, limit dextrinase, and α-glucosidase, act sequentially to break down the dextrin molecule into smaller units.

The sequential hydrolysis produces a mixture of shorter dextrin chains and individual glucose molecules. Ultimately, the process results in the complete digestion of dextrins into glucose, which is then absorbed into the bloodstream and utilized for energy production.

Dextrin catabolic process is essential for obtaining energy from dietary starch. It allows the body to break down complex carbohydrates into a form that can be readily absorbed and used by cells. Disruptions in this process can lead to various digestive issues, such as malabsorption and diarrhea.'
