Day 30 of 30: Peptides 101
Peptides are short chains of amino acids—the same fundamental building blocks that make up proteins—but they are typically much smaller and more targeted in function, which gives them a unique and powerful role in biology. In the human body, peptides act as messengers and regulators, influencing processes such as hormone signaling, immune response, tissue repair, metabolism, and neurological communication. For example, insulin is a peptide hormone that regulates blood sugar, while collagen peptides contribute to skin, joint, and connective tissue health. Because peptides are composed of naturally occurring amino acids, the body can often recognize and break them down efficiently, which is one reason they’ve become a major focus in modern medical research. Scientists can design specific peptides to bind to particular receptors, essentially “telling” cells what to do—such as stimulating growth hormone release, reducing inflammation, accelerating wound healing, or modulating appetite and energy balance. This precision has made peptides valuable in therapeutic development, including treatments for diabetes, autoimmune conditions, cancer research, and age-related degeneration.
