Hydrolysis literally means "breaking with water". It's a chemical process where water molecules are used to break down larger molecules into smaller ones.

Here's how it works:

* Water molecule (H₂O) splits: The water molecule breaks into a hydrogen ion (H⁺) and a hydroxide ion (OH⁻).

* Bonds break: These ions interact with the larger molecule, breaking its chemical bonds.

* New molecules form: The broken pieces of the original molecule combine with the hydrogen and hydroxide ions, forming new molecules.

Hydrolysis is a crucial process in many biological and chemical reactions, including:

* Digestion: Breaking down food molecules into smaller units that the body can absorb.

* Cell metabolism: Breaking down complex molecules for energy production.

* Polymer synthesis: Breaking down polymers into monomers.
