Give 4 examples of pairs of polar amino acids that might be substituted for each other with little effect on protein function due to the amino acids having the same functional group. For each pair, name the functional group they have in common.

Classify these amino acids as acidic, basic, neutral polar, or neutral nonpolar.

Classify these amino acids as acidic, basic, neutral polar, or neutral nonpolar. Glutamic Acid, Tyrosine, Threonine, Valine, Tryptophan

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....

Consider an ion channel membrane protein: •Even amino acids with non-polar R groups have unavoidable polar regions—where? •Given this, why do you suppose most transmembrane domains exist as α-helices or β-sheets (what does this allow?) •Describe the types and locations of amino acid R groups that would be found at various surfaces of this ion channel. How would this contribute to the pore’s function as an ion channel?

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...
