Here's a breakdown:

* Proteins are long chains of amino acids linked together by peptide bonds.

* Hydrolysis is a chemical reaction that uses water to break down a molecule.

* In the case of protein hydrolysis, the water molecule breaks the peptide bonds, separating the amino acids from each other.

Think of it like this:

Imagine a string of beads (the protein) connected by knots (the peptide bonds). Water (the hydrolysis agent) comes in and breaks the knots, releasing the beads (the amino acids).

The specific amino acids produced depend on the original protein sequence. There are 20 different amino acids commonly found in proteins.
