Is conversion of glucose units into starch an example of hydrolysis?

No, the conversion of glucose units into starch is not an example of hydrolysis; it is a process called polymerization. In this process, glucose molecules are linked together through glycosidic bonds to form the polysaccharide starch. Hydrolysis, on the other hand, involves the breaking down of complex molecules into simpler ones, typically with the addition of water, such as the breakdown of starch into glucose.
