KEGG is like a big map of living things. Sometimes we need maps to help us find our way around a new place, right? Or to see how all the roads and buildings fit together. KEGG is like that, but for living things.
It shows how different things in living things are related to each other. Like, how different chemicals and molecules help make living things work. It also shows how these things work together in living things like animals and plants.
It's like a big picture that scientists use to study and understand living things better. They use it to see how different genes and molecules in living things work together to help them survive and grow. Kind of like how we need food, water and air to stay healthy, living things have their own set of things they need to live and grow.
So, KEGG is a really helpful tool for scientists to study living things and understand how they work. And who knows, maybe one day you'll use KEGG too!
