Now, the three most common disaccharides in the human body are maltose, sucrose, and lactose. Now, maltose is basically obtained by the digestion of the carbohydrate we call starch. So our body breaks down starch into maltose. And maltose consists of two glucose molecules that are attached via an alpha one four glycocitic bond. And the enzyme found on the Brush border that breaks down Maltose into two glucose molecules is known as maltase. Now, for sucrose, sucrose consists of our glucose and fructose attached via an alphagly acidic bond.
