What bond occurs between and within molecules which stabilize structures such as proteins and nucleic acids?

• Hydrogen bond

• Hydrophobic bond

• Ionic bonds

• van der Waals forces

What bond has a very weak interaction between non-polar molecules that is important in protein shape and membrane structure?

• Hydrogen bond

• Hydrophobic bond

• Ionic bonds

• van der Waals forces

What bond occurs between two oppositely charged particles which is the stongest noncovalent force that occurs over greater distances? This bond also can be weakened significantly by water molecules which water can interfere with bonding.
