ELI5: Explain Like I'm 5

Primary structure

The primary structure is like a blueprint for everything in our body. Just like how a builder starts with a plan to make a house, our body starts with a plan to make different types of proteins. This plan is called the primary structure.

Think of it like a really long sentence that tells the body how to make a protein. The sentence is made up of letters, just like the primary structure is made up of different types of molecules called amino acids. Each amino acid is like a different letter in the sentence.

When the body wants to make a protein, it reads the primary structure like a book and starts putting the amino acids together in a specific order, just like we put letters together to make words in a sentence. This order is super important because it determines what kind of protein will be made and what it will do in the body.

So, the primary structure is like a very important instruction manual that tells the body how to make different proteins, which help us grow and stay healthy.
