What happens to onions when cooked?
When onions are being cooked, the heat from the pan raises the temperature within the cells of the onion. Once the temperature is high enough, the poly- and disaccharides in the onion are broken down into monosaccharides by breaking the bonds that link the monosaccharides to each other.
