Peptides are short chains of amino acids, typically containing 2-50 amino acids. They play many important roles in the human body such as signaling between cells, regulating bodily functions, and even fighting off pathogens. Some key examples of peptides include:
- Oxytocin - the "love hormone" involved in childbirth, bonding, and social interactions
- Endorphins - natural pain relievers released in response to exercise and other stimuli
- Angiotensin - helps control blood pressure by constricting blood vessels
- Glucagon - regulates blood sugar levels by triggering the release of glucose into the bloodstream
Peptides can also be used therapeutically due their ability to target specific cells and pathways. For example, the peptide
insulin is used to manage diabetes, while other peptides show promise in areas like wound healing, immune modulation, and even slowing aging.
Researchers are also studying whether tweaking natural peptide sequences or developing entirely new peptides could generate novel drugs. However, more research is still needed to fully understand the diverse roles of peptides in health and disease.
