Here's why:

* Hydrolysis means "breaking down with water."

* In a hydrolysis reaction, a water molecule (H₂O) is added to a molecule, breaking it into two smaller molecules.

* This is the opposite of a dehydration reaction, which removes water to join molecules.

Example:

* Hydrolysis of sucrose (table sugar):

* Sucrose + Water → Glucose + Fructose
