Enzymes are special types of proteins. Like all proteins, enzymes are made from strings of amino acids. The function of the enzyme is determined by the sequence of amino acids, types of amino acids, and the shape of the string.
Amylase is an example of an enzyme. Amylase is found in our saliva and is responsible for starting to break down the starch that we eat. So amylase is an enzyme that carries out the specific reaction of breaking down starch into a simple sugar.An enzyme breaks down larger molecules into smaller molecules like sugars. -An enzyme is specific for its substrate: the enzyme that breaks down starch won't be able to break proteins down. -An enzyme is reusable, it doesn't get used up in the reaction, so it can perform it over and over again.
