Protein secondary structure

Proteins are like big bags of Legos made up of smaller pieces called amino acids. Just like different Legos can be put together to make different things, amino acids can be put together in different ways to make different proteins.

When amino acids come together to form a protein, they can fold up in different shapes. There are two main shapes that proteins can fold into: a helix shape, which looks like a curly telephone cord, or a sheet shape, which looks like a flat sheet of paper.

These shapes are called secondary structures. They are important because they help determine what the protein does and how it interacts with other things in the body. For example, a protein with a lot of helix shapes might be really strong, while a protein with a lot of sheet shapes might be really flexible.

Scientists use fancy tools to study the secondary structure of proteins and figure out what shapes they have. Knowing the secondary structure of a protein can help us understand how it works and how we might be able to use it to our advantage.
