Sort each peptide chain as part of a parallel %u03B2 sheet, part of
an antiparallel %u03B2 sheet, either (cannot determine if parallel
or antiparallel), or not part of a %u03B2 sheet (for example, if it
is part of an %u03B1 helix). Be as specific as possible. For
example, if a given structure is a parallel %u03B2 sheet, identify
it as such.
Part A Which is not true about beta-sheets? Antiparallel sheets provide better hydrogen bonding than parallel sheets Antiparallel is when two peptide strands run in opposite directions The sheets are pleated The side chain of the residues are side-by-side (planar) to the peptide backbone

The secondary structure shown below is an example of an) N N A beta turn B. parallel beta sheet C antiparallel beta sheet D. right handed alpha helix Which amino acid would be most stabilizing at the N-terminus of an a-hellx (pH=7.0)? A Lysine B. Asparagine C Glutamine D. Glutamate
A β-pleated sheet, contained within a globular protein, has two parallel strands connected by a turn. The turn is called a “beta-alpha-beta” motif. The α-helical portion (the turn) consists of 34 amino acids. The molecular weight of the entire sheet (including the α-helix) is 9.7 kd. What is the approximate length (i.e., the longest dimension) of this β-pleated sheet? Assume that the α-helix does not contribute to the length of the β-pleated sheet. (HINT: Since the amino acids in this...
Question 5. Which of the following pairs of bonds within a peptide backbone show free rotation around both bonds? A) Ca-C and N-C B) C-O and N-C C) C-O and N-Ca D) N-C and Ca-C E) N-Ca and N-C Question 6. In the diagram below, the plane drawn behind the peptide bond indicates the: A) absence of rotation around the C-N bond because of its partial double-bond character. B) plane of rotation around the C-N bond. region of steric hindrance...
Understand alpha helices and beta pleated sheets Question How is it possible for the a-helix to have amino acids with bulky side chains while the B-pleated sheets cannot? Select the correct answer below: O The R groups in the a-helix stabilize the structure, while they interfere with the hydrogen bonds in a B-pleated sheet. The R groups are contained inside the a-helix structure, while they interfere with the hydrogen bonds in a B- pleated sheet. O The R groups lie...
