What are proteins and why do they need to fold?
They are nature’s nanomachines. Proteins are the molecules in the body that it uses to get everything done. They act as catalysts to speed up chemical bonds that might take a billion years through other types of biological machinery. So whenever something needs to get done in biology, odds are, proteins are at work. They all have different functions, some are like scissors, some bring bonds together. If you think about the use of building nanomachines today, biology solved this millions of years ago. It amazes how well this works in the body.
