Peptide facts for kids
Peptides are tiny chemical building blocks. They are like small chains made from even smaller units called amino acids. Imagine amino acids as individual LEGO bricks. When you link these bricks together in a specific order, you get a peptide chain. The special connection between these bricks is called a peptide bond. When many peptides link up, they form larger molecules called proteins. Proteins are super important for almost everything in your body!

What are Peptides?
Peptides are small molecules found in all living things. They are made by connecting amino acids in a specific order. Think of amino acids as the basic letters, and peptides as short words or sentences made from those letters. The way these letters are arranged gives each peptide a unique job.
How Peptides are Built
Peptides are formed when amino acids join together. This joining happens through a special link called a peptide bond. It's like snapping two LEGO bricks together. Each time an amino acid is added, a new peptide bond is formed, making the chain longer. The order of the amino acids is very important, just like the order of letters in a word changes its meaning.
Peptides and Proteins
Peptides are often called "mini-proteins." When many peptides link up, they form much larger molecules known as proteins. Proteins are also called polypeptides. So, peptides are the smaller parts that make up the bigger, more complex proteins. Proteins do most of the work in cells and are needed for the structure, function, and regulation of the body's tissues and organs.
What Do Peptides Do?
Peptides have many important jobs in your body. They act like messengers, carrying signals between cells. For example, some peptides are hormones that control things like growth or how you feel hunger. Others help your body fight off germs, control your blood pressure, or even help you sleep. They are involved in almost every process that keeps you healthy and alive.
