What is a difference between parallel and antiparallel -sheet secondary structures?
A) Antiparallel -sheets have a larger number of stabilizing H bonds between backbone amides than parallel -sheets.
B) Parallel -sheets require a larger loop connecting together the individual peptide strands in the sheet.
C) Parallel -sheets are longer than antiparallel sheets.
D) Parallel -sheets have amino acid side chains alternating up and down, whereas antiparallel side chains alternate down and up.
