How do lipids differ from other macromolecules like carbohydrates and proteins?
Understand the Problem
The question is asking about the differences between lipids and other types of macromolecules, specifically carbohydrates and proteins. It presents multiple options to choose from, clarifying the unique characteristics of lipids.
Answer
Lipids are hydrophobic, not water-soluble, and don't form long polymers.
Lipids differ from other macromolecules like carbohydrates and proteins as they are hydrophobic, not water-soluble, and do not form long polymers or repeating units.
Answer for screen readers
Lipids differ from other macromolecules like carbohydrates and proteins as they are hydrophobic, not water-soluble, and do not form long polymers or repeating units.
More Information
Lipids are unique among the main classes of macromolecules because their structures are nonpolar, contributing to their insolubility in water, which is central to many of their biological functions, such as forming cell membranes.
Tips
Students often mistakenly think lipids are similar to proteins and carbohydrates in terms of structure and chemical properties. It is important to remember that the hydrophobic nature and lack of polymer formation are key distinguishing features.
