What are the main similarities and differences between a 310 helix and alpha helix. I know that a 310 helix has 3 resiudes per turn and an alpha helix has 3.6 but what other the other differences and simlarities between the 2?

I don't know the answer to this question, but the kinds of questions I would ask about any helix would be handedness, hydrogen bonding patterns, and translation of the helix per unit residue.

One more thing for protein helices.  I would ask what are the values of the dihedral angles, phi and psi, and whether or not they fall into the allowed region of the Ramachandran diagram.
