Homework Answers
Ans 1: antiparallel beta sheet.
Antiparallel beta sheet consist of polypeptide chain running in opposite directions, i.e. one is N terminal to C terminal and the other polypeptide is C terminal to N.
Ans 5: x-ray crystallography.

Sort each peptide chain as part of a parallel fi sheet, part of an antiparallel beta sheet, either (cannot determine if parallel or antiparallel), or not part of a fi sheet (for example, if it is part of an alpha helix). Be as specific as possible. For example, if a given structure is a parallel fi sheet, identify it as such.
