Peptides are short chains of amino acids linked by peptide bonds, and they play crucial roles in various biological processes. Typically consisting of 2 to 50 amino acids, peptides can function as hormones, signaling molecules, or components of proteins, influencing processes such as metabolism, immune response, and cell signaling. Each type of peptide has unique functions that are essential for maintaining overall body health.
1. Hormonal Peptides: These peptides act as hormones and regulate various physiological processes.
2. Neuropeptides: These are involved in transmitting signals in the nervous system. They can modulate pain, stress, and emotions.
3. Antimicrobial Peptides: These peptides are part of the immune system and provide a first line of defense against pathogens.
4. Structural Peptides: These peptides contribute to the structural integrity of tissues like Collagen.
5. Growth Factors: These peptides stimulate cellular growth, proliferation, and differentiation.
