Detailed explanation-2: -Water, without any doubt, must be considered an integral part of biological macromolecules. The living world should be thought of as an equal partnership between proteins, nucleic acids and water.

Detailed explanation-3: -Final answer: Sucrose is not a macromolecule.

Detailed explanation-4: -Lipids, also commonly known as fats, are composed primarily of carbon and hydrogen. Due to this, lipids are predominantly hydrophobic molecules that do not dissolve with water.

Detailed explanation-5: -The large molecules required for life built from smaller organic molecules are called biological macromolecules. There are four major biological macromolecules classes: carbohydrates, lipids, proteins, and nucleic acids.
