What Are Peptides?

Peptides are short chains of amino acids linked by peptide bonds and are considered the building blocks of proteins. These molecules are naturally occurring in the body and play a crucial role in many biological functions. Unlike proteins, peptides are smaller, typically comprising 2 to 50 amino acids. This smaller size allows them to be more easily absorbed and utilized by the body, making them significant in therapeutic applications.
