What Are Peptides?

Peptides are tiny chains made of amino acids, kind of like a necklace made of beads. Your body uses peptides for important jobs, like helping muscles grow, healing wounds, or sending messages between cells.

Amino Acids

These are the building blocks of peptides and proteins. Think of them as Lego pieces. Each piece is slightly different, and when you snap them together, you can build different shapes and structures. Your body has 20 main amino acids it uses to build everything it needs.

Protein

Proteins are big chains of amino acids, while peptides are small chains. Proteins do huge jobs in your body: they make your hair, muscles, skin, and help fight germs.

Cells

Cells are tiny building blocks of your body. Everything in your body is made of cells, kind of like how a Lego house is made of little Lego bricks.

Hormones

Some peptides act as hormones, which are messengers that travel around your body to tell it what to do. For example, insulin is a hormone that helps control sugar in your blood.

Receptors

These are like locks on the surface of cells. Peptides are the keys that fit into these locks to send messages to the cell.
