Glycine and proline are both non-polar amino acids, and both are very likely to be found at the surface of proteins. What physical characteristic of each is responsible for this observation?

1) Both glycine and proline are small.
2) Glycine is small, and proline is rigid.
3) The side chains of both these amino acids make favorable interactions with molecules near the surface of proteins.
4) Both amino acids make strong interactions with each other and therefore are likely to be found next to each other in a protein.

Only statement 2 is correct.
Only statements 1 and 2 are correct.
Only statements 2, 3, and 4 are correct.
Only statements 1, 2, and 3 are correct

Researchers have described the “binary patterning” of polar and nonpolar amino acids in the sequences of proteins. In their code, polar and charged residues like D, N, E, Q, K, H, and R are represented as open circles (○) and nonpolar residues like F, L, I, M, and V as closed circles (●). Thus, a polypeptide with the sequence asp-ile-his-phe-gln would be represented as ○●○●○. Researchers analyzed the binary patterns of isolated secondary structure elements (short pieces) from native proteins....

You have accidentally mixed a bunch of amino acids (tryptophan, tyrosine, alanine, selenocysteine, proline, arginine) together and once your boss finds out, you will be fired on the spot. Your only hope of saving your job is to separate them before anyone finds out. You decide that the only viable option is to use ion exchange chromatography. Explain, in detail, how you would do this?
