The fact that each enzyme product on the market has its own unit system can be confusing, particularly when attempting to compare similar products.

Enzymes are natural proteins that act as biological catalysts. Catalysts accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.

Enzymes are natural proteins that break down large feed components into more minor simple compounds. These simple compounds are then absorbed to be used by the animal for maintenance and production.
