The Science of Peptides
Understanding the fundamental building blocks of peptide therapeutics
What Are Peptides?
Peptides are short chains of amino acids (typically 2–50) linked by peptide bonds. They serve as signaling molecules in the body, triggering specific biological responses in cells and tissues.
How They're Made
Bioactive peptides can be naturally derived from proteins through enzymatic hydrolysis, or synthetically manufactured through solid-phase peptide synthesis (SPPS) in laboratory settings.
Scientific Purpose
Peptides were originally developed as research tools to study receptor-ligand interactions. Many have since shown therapeutic potential in areas like tissue repair, immune regulation, and metabolic control.
Clinical Research
Hundreds of peptides are currently in clinical trials worldwide. Their high specificity, low toxicity, and predictable metabolism make them attractive candidates for next-generation therapeutics.
