What Are Peptides? A Biochemical Overview
At their most basic level, a peptide is a short string of 2 to 50 amino acids, formed by a condensation reaction, joining together through a covalent bond. These molecules are essentially the building blocks of proteins, yet they act with a level of specificity that makes them fascinating to study. Because they are molecules made up of two or more amino acids connected by a peptide bond, they participate in diverse biological roles, ranging from signaling molecules and hormones to neurotransmitters.
When reviewing the literature, it becomes clear that members of the class of compounds composed of amino acids joined together by peptide bonds into linear, branched, or cyclical structures are fundamental regulators of metabolism. My interest in this field grew as I learned that these compounds act as transmitters from the brain to the body, influencing physiological processes in ways that are still being mapped by researchers today.
