The alpha-helix structure is stabilized by:.
1. covalent bonds between adjacent functional groups.
2. hydrogen bonds along the peptide backbone.
3. association with helixase stabilizing enzymes.
4. non-covalent interactions with water.
5. cationic elements found in water solutions.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
