**What This Document Is**
This document is a detailed exploration of peptides – short chains of amino acids – and their significant roles in biological systems. Specifically, it focuses on peptides that exhibit demonstrable biological activity, meaning they function as signaling molecules or have direct physiological effects within the body. It delves into the complex relationship between these peptides and the enzymes, known as peptidases, that regulate their activity. The material originates from a PCOL 425 Medical Pharmacology course at the University of Illinois at Chicago.
