What is the role of van der Waals interactions in biological molecules?
1. Van der Waals interactions are strong bonds that play a major structural role in holding proteins together.
2. Although they are weak bonds, van der Waals interactions involve the sharing of electrons.
3. Van der Waals interactions are important only in water.
4. Although they are weak bonds, van der Waals interactions help to reinforce the three-dimensional shapes of large molecules.
5. Van der Waals interactions are too weak to be significant.
Answer: 4. Although they are weak bonds, van der Waals interactions help to reinforce the three-dimensional shapes of large molecules.
