Introduction - This script shows some properties of the parallel
β-strand. Scroll down until the text corresponding to the view
is visible.

In this "peptide" the phi and psi angles have been set to those
corresponding to a parallel β-strand.

Here we see the hydrogen bonds formed between two strands of a
parallel β-sheet.

In this view we see the "pleats" of a parallel β-sheet. Note
how the sidechain groups point alternatively above and below the
plane of the sheet.
