Q: Answer the following question given this paragraph: The simple sugars form the foundation of more complex carbohydrates. The cyclic forms of two sugars can be linked together by means of a condensation reaction. The figure below shows how a glucose molecule and a fructose molecule combine to form a sucrose molecule. A hydrogen atom from one molecule and a hydroxyl group from the other molecule are eliminated as water, with a resulting covalent bond linking the two sugars together at that point. Q: During the condensation reaction of sugars what is removed, linking the two sugars? Choices: - hormones - chlorophyll - air - water A:
