Definition & Meaning: Ase Word Root

The root word “ase” comes from the Greek “diastasis” meaning “separation” and is primarily used to form the names of various types of enzymes. For instance, the word “Amylase” is an enzyme that converts starch to sugar. Here’s the breakdown:

  • Amylum: Starch
  • -Ase: Suffix for enzyme
  • Amylum + -Ase: Amylase, i.e., an enzyme that converts starch to sugar

It is fair to say that words with the word root “ase” are mostly used to represent enzymes.

Example sentence: Hydrolases are the types of enzymes which help in food digestion and food decomposition.
