Verified step by step guidance

Identify the role of functional groups in macromolecules. Functional groups are specific groups of atoms within molecules that have characteristic properties and chemical reactivity.

Understand that functional groups are not limited to proteins. They are present in various macromolecules, including carbohydrates, lipids, and nucleic acids.

Recognize that functional groups significantly affect the solubility of macromolecules. For example, hydroxyl groups (-OH) can increase solubility in water due to their ability to form hydrogen bonds.

Acknowledge that functional groups determine the chemical reactivity and properties of macromolecules. They are responsible for the specific chemical reactions that a molecule can undergo.

Clarify that functional groups can be polar or non-polar, hydrophilic or hydrophobic, depending on their composition. For instance, carboxyl groups (-COOH) are polar and hydrophilic, while methyl groups (-CH3) are non-polar and hydrophobic.
