How does the carbon, hydrogen and oxygen atoms in glucose and fructose combine to form sucrose?

Question

Please include in your description which atoms bonded together from fructose and glucose to form sucrose and which atoms reformed to create a water molecule.

Answer 1

Look at the ring structures of both molecules, with fructose on the left. Where could two rings be bonded by taking a hydrogen off a hydroxyl group (OH) and losing a hydroxyl group off the other sticking the two molecules into one with a common oxygen?
