What is a Peptide?

Peptides are short chains of amino acids linked by peptide bonds. Typically, peptides contain less than 50 amino acids. Anything longer is considered a protein.

Peptides serve many important biological functions. For example:

• Some peptides act as chemical messengers that help regulate bodily processes like blood pressure, pain perception, and appetite. These messenger peptides are also called hormones.
• Other peptides play key roles in the immune system, defending the body against pathogens.
• Special peptides in the brain act as neurotransmitters that nerve cells use to communicate with each other.

There are several key features that distinguish peptides:

• Size: Peptides are short, typically less than 50 amino acids. Proteins are longer chains, over 50 amino acids.
• Structure: The peptide chain can fold into different 3D shapes like alpha helices and beta pleated sheets. These shapes determine the peptide's function.
• Function: Peptides have many biological functions and are often considered the bridge between large proteins and tiny molecules.

How are peptides made in the body?

Peptides form when the protein assembly machinery in cells, called ribosomes, link amino acids together into chains. Enzymes can then cut these longer protein chains into smaller peptide fragments.

What's an example of a peptide hormone?

Insulin is a great example. This peptide helps control blood sugar levels. People with diabetes often lack sufficient insulin.
