In a way that involves the breakdown of proteins into smaller peptides or amino acids.
The enzyme works proteolytically to help digest food in the stomach.
Proteolytically → It is formed from "proteo-" (from Greek "proteios", meaning primary or first) and "lytic" (from Greek "lytikos", meaning able to loosen or dissolve) and the suffix "-ally" (meaning in a manner). The word refers to the manner in which proteins are broken down or dissolved.
Think of 'primary' ('proteo-') proteins being 'loosened' or 'dissolved' ('lytic') — that's how proteolytically describes the process of breaking down proteins.
