A coenzyme is a small, organic, non-protein molecule that binds with or attaches itself to a protein molecule to form an active enzyme. Enzymes are found in almost all living organisms and have very important roles, for example, to aid in digestion. An active enzyme’s purpose is to facilitate and speed up a chemical reaction.

Vitamins B1, B2, and B6 are examples of water soluble enzymes that serve as coenzymes. Another example of an enzyme is Amylase. Amylase helps change starches into sugars.
