Understanding Peptides
What Are Peptides and Their Functions?
Peptides are short chains of amino acids linked together by peptide bonds. They play crucial roles in various biological functions including hormone regulation, immune response modulation, and cellular signaling. Depending on their length, peptides can perform differently; for instance, small peptides may serve as signaling molecules, while larger ones can have more complex functions like enzymatic activities. The study of peptides has gained significant attention as a potential frontier in therapeutic development, particularly in the realms of medicine and biotechnology.
