What are proteins?

Proteins are like tiny workers that help your body do all sorts of important jobs.

Imagine you have a big box of LEGO bricks. Each brick is a little piece that can fit together with others to make something bigger, like a car or a house. Proteins are kind of like those LEGO bricks, they're made from smaller pieces called amino acids, and when these pieces link up, they create different kinds of proteins that do special things in your body.

Proteins can be strong like ropes, helping you move; smart like a puzzle piece, fitting into other parts to help with reactions in your body; or even messengers, telling your cells what to do.

Just like how different LEGO shapes make different things, the way amino acids connect makes each protein unique. Some proteins are used to build muscles, others help you digest food, and still others protect you from germs.

So next time you play with your LEGO bricks or eat a snack, remember, your body is using its own kind of LEGO every day!
