Amylase is an enzyme that breaks down starch into sugars during digestion. Found in saliva (spittle) in humans and some mammals, amylase kickstarts the process of carbohydrate digestion. When foods high in starch, like rice and potatoes, are chewed, they may develop a slightly sweet taste as amylase begins converting the starch into simpler sugars. This enzyme plays a crucial role in the early stages of digestion by helping to break down complex carbohydrates.
