relative strengths of bonds in proteins.

I need some help to order these different bonds that appear in protein structural levels in order of their relative strength. (i.e. weak --> strong)

Disulfide bonds
Electrostatic forces
hydrogen bonds
hydrophobic forces

Its should be

1 Hydrophobic Bonds
2 Electrostactic
3 Hydrogen Bonds
4 Disulfide Bonds

I'm not sure....can someone confirm? I don't think Hydrophoic "Bonds" are actually bonds because its only due to their polar tails and heads which causes them to stick together (Also known as electrostatic??)

What school are you in? Interesting to know coz only >10% of the state does this.

i'd say the way you orderd those is probably correct, however 2 and 3 might be the other way around. Can somone clarify this?

Electrostatic are different to hydrophobic i thought, hydrophobic bonds influence the tertiary structure of the protein as the hydrophobic ends of the molecules clump together in the presence of water(?). Whlist electrostatic forces form when an end of the protein molecule looses as proton the the opposite side gains, causing many molecules to interact through the attraction of -ve and +ve charge.
