Peptides are short chains of amino acids linked by peptide bonds. They are essentially small proteins that play many important roles in the body. Some key things to know about peptides:
- Peptides are made up of 2 to 50 amino acids. This makes them much smaller than proteins, which contain hundreds or thousands of amino acids.
- There are many different types of peptides, including neuropeptides, signal peptides, opioid peptides, antimicrobial peptides and more. Each type has specific functions.
- Many peptides act as signaling molecules that help cells communicate. For instance, insulin is a peptide hormone that regulates blood sugar levels.
- Some peptides have potent biological effects and are used as medicines. For example, oxytocin promotes bonding and social interactions.
Now let's dive deeper into the biology and function of these important molecules:
- Peptides are synthesized by linking amino acids together via peptide bonds. This bond forms when the amino group of one amino acid reacts with the carboxyl group of another.
- The sequence and number of amino acids determine the peptide's structure and function. Even small differences in sequence can significantly alter bioactivity.
- Cells use peptides for cell signaling. When secreted, peptides can interact with receptors on target cells. This activates signal transmission pathways.
- Many peptides act as hormones that coordinate responses between tissues and organs. Examples include insulin, oxytocin and angiotensin.
- The nervous system uses neuropeptides to regulate pain, appetite, mood and cognition. Well-known neuropeptides include endorphins and enkephalins.
- Peptides play a key role in the immune system. Some have direct antimicrobial effects, while others influence inflammatory responses.
- Peptides have great pharmaceutical potential due to their potent and specific effects. Synthetic versions include liraglutide for diabetes and lupron for cancer.
Overall, peptides are versatile signaling molecules with diverse biological functions. From influencing behavior to fighting infection, they play integral roles in regulating physiology. Exciting advancements in peptide drug development are also underway.
