- What general structural feature is shared by proteins that specifically form homodimers (but not homotrimers, homoteramers etc)? Only one answer is correct. the surface consists of hydrophilic alpha-helix. the surface is highly modified by post-translational modification. the surface is permanently bound by chaperones. the surface is unstructured. the surface, or part of it, is self-complementary.Which of the following statements about alpha-helix and beta-sheet structure are true? More than one answer is correct. -they are aspects of protein secondary structure. -they are maintained by hydrogen-bonding interactions within the polypeptide backbone. -most proteins fall into one of two categories: those composed entirely of alpha-helix, and those composed entirely of beta-sheet. -in both alpha-helix and beta-sheet, each amino acid (at position n) interacts with another amino acid at position n+4. -alpha-helix contains only hydrophobic amino acids, while beta-sheet contains only hydrophilic amino acids. More than one answer is correct I am confusedThe structure of an alpha helix orients the oxygens of the carbonyl group of the peptide bond towards the C-terminal end of the helix while the hydrogens of the NH groups orient toward the N-terminal end, thus imparting a dipole along the length of the helix. As a result, which kinds of amino acids would favor the C-terminal end, and which would favor the N-terminal end? negatively charged, positively charged positively charged, negatively charged negatively charged, hydrophobic positively charged, hydrophobic hydrophobic, negatively charged hydrophobic, positively charged

H-I-R-E-F A-D-L-E-E A-D-E-L-E C-V-D-E-FFor the three peptides below, label whether they would form an amphiphilic beta-strand, amphiphilic helix, or nothing. Explain why. Part a) S-V-K-I-Q-M-R-A-D-L Part b) A-L-E-H-M-F-R-Y-L-A-K Part c) A-L-A-I-W-F-P-D-R-K-EFor transmembrane proteins, either single-pass or multi-pass, the membrane spanning part of the protein usually assumes which of the following motifs? βαβ αβα α-helix β-pleated sheet
- Alpha-helices have 3.6 amino acid residues per turn, ie a helix 36 amino acids long would form 10 turns, and The axial distance between adjacent residues is 3.5 Angstroms. Beta-helices have two residues per repeat unit which gives the beta-strand a 7 Angstrom pitch. This compares with the alpha-helix where the axial distance between adjacent residues is only 1.5 Angstroms. Then how many residues in an alpha-helix conformation would it take to traverse the same distance as 10 residues in beta-strand conformation?The following is a segment of the primary structure of an α-helix:N terminus.......– amino acid 1 – amino acid 2 – amino acid 3 – amino acid 4 – amino acid 5 – amino acid 6 – amino acid 7 – ......Which amino acid residue forms a hydrogen bond with the backbone of amino acid 3 to stabilize the helix? a. Amino Acid 1 b. Amino Acid 3 c. Amino Acid 5 d. Amino Acid 7Which of the following peptides will likely adopt an alpha helix structure? (idk) A-D-I-E-L-Y-F-H-I-C-V-D A-R-E-P-H-Y-D-P-C-Q-S A-D-I-E-L-Y-M-H-I-C-V-D A-R-E-V-H-Y-I-D-C-Q-F
- Which of the following statements are true? The local folding of the polypeptide in some regions gives rise to the secondary structure of the protein. The most common secondary structures are the α-helix and β-pleated sheet structures. Certain amino acids have a propensity to form an α-helix, while others have a propensity to form a β-pleated sheet. Select the correct answer below: 1 and 2 1 and 3 2 and 3 all of the aboveWithin a naturally-occurring polypeptide, under neutral pH conditions (pH = 7.0), which of the following amino acids always has a positively charged amine group?
