The process of digestion of carbohydrates starts from mouth. There is an enzyme in our saliva which is known as amylase. This enzyme starts digesting carbohydrates in the mouth and converts the complex carbohydrates into simpler types. When these carbohydrates enter the stomach then an enzyme activity continues in the stomach. There are digestive acids in the stomach which are released into the stomach by the glands. When these carbohydrates enter the small intestine then amylase is secreted by the pancreas into the duodenum. Now, carbohydrates are converted into simple sugars including maltose, lactose and sucrose. The further processing on carbohydrates in intestine by the enzymes maltase, lactase and sucrase further divides the carbohydrates into smaller bits so that they can be more easily absorbed.
