The human body uses protein in innumerable ways. They are the building blocks of your body, and it's many functions. Your cells are continually manufacturing proteins; while you sleep, walk or even now as you read this blog.
Proteins make up cellular channels, are structural, act as enzymes, and are part of your immune system. These proteins are formed as strings and can be very long. Folding proteins - just as folding laundry - give them organization, condenses their size, but unlike you laundry it also provides function.
The human body is made up of cells, and inside these cells are millions of tiny machines made up of folded proteins. These are found in every single living thing.
These proteins are folded into a specific shape to allow them to function.
If you unfold one, you'll find a string of amino acids - like beads on a necklace. These long strings of amino acids only function once they have folded into a specific shape. If the shape is slightly off, the protein will not function.
Once scientists understand how proteins fold, they will be able to develop methods to cure and prevent innumerable diseases.
