WebIn a beta sheet, the amino acid side chains in each strand are alternately position above and below the sheet, and the carboxyl oxygens alternate from one side of the strand to the other. Thus, each strand in a beta sheet can be viewed as a helix in which each successive amino acid is rotated 180 degrees.
