Hydrolases are a type of enzyme that help break down larger molecules by adding water. They play a crucial role in various biological processes, such as digestion, where they help convert complex carbohydrates, proteins, and fats into simpler forms that the body can use. For example, the enzyme amylase breaks down starches into sugars in the mouth and small intestine. These enzymes are essential for many metabolic pathways and are found in all living organisms. Hydrolases can be classified into different categories based on the type of bond they break, such as proteases for proteins and lipases for fats. Their activity is vital for maintaining overall health and supporting cellular functions.
