Expasy is like a big and magical library for scientists, but instead of books, it has lots and lots of information about proteins.
Just like how we have different parts in our body, proteins have different parts too. Expasy helps scientists understand these parts and gives them information about what each part does and how it works.
Scientists can also use Expasy to learn about how different proteins are related to each other and how they interact. This is important because proteins are involved in many different functions in our body, like helping our muscles move and digesting our food.
Overall, Expasy is a really helpful tool for scientists to learn more about proteins and how they work in our bodies.
