5. Secondary structure (B-sheet): The image below is of a polypeptide in secondary (2) structure level of protein folding. Specifically it is of a B-sheet. The image on the left is of an anti-parallel sheet, and the right of a parallel sheet. a. Name the specific bond/interaction indicated by the dotted lines. b. Is this bond/interaction covalent or non-covalent? c. Is this bond/interaction permanent or transient? d. What parts of the amino acid (backbone or side chain) are...
