Alpha-amylase is an enzyme that helps break down starches into sugars. It is produced in the saliva of humans and in the pancreas, playing a crucial role in digestion. This enzyme works by cleaving the bonds between glucose units in starch, making it easier for the body to absorb nutrients. In addition to its natural occurrence in the body, alpha-amylase is also used in various industrial applications. It is commonly found in the food industry, where it helps in the production of sweeteners and in baking. Moreover, it is utilized in the textile and paper industries for processing starch-based materials.
