Introduction to Peptides

What are Peptides?

A peptide is a short chain of amino acids linked together by peptide bonds. Amino acids are the building blocks of proteins, and peptides are smaller versions of proteins. Peptides act as hormones, neurotransmitters, and signaling molecules. They can influence physiological processes such as growth, metabolism, and immune responses.

Peptides can be naturally produced or synthesized in the lab for research use. They interact with specific receptors to influence biological processes.

Types of Peptides

Neuropeptides

Neuropeptides act on the nervous system and are involved in regulating mood, pain, and stress responses. They play crucial roles in communication between neurons. DSIP (Delta Sleep Inducing Peptide) is an example.

Hormonal Peptides

Hormonal peptides regulate various physiological functions, including growth, metabolism, and reproduction. Examples include insulin and growth hormone.

Antimicrobial & Restorative Peptides

Antimicrobial peptides help defend against infections by targeting and destroying pathogens such as bacteria and viruses. BPC-157 and Epithalon are peptides researched for their regenerative properties.
