The sheet shown below is composed of four strands. All the atoms are shown (C = green; N = blue; O = red; S = yellow; H = white). This is a mixed β-sheet. Some of the strands are parallel, some are antiparallel. | The sheet shown below is composed of four strands. All the atoms are shown (C = green; N = blue; O = red; S = yellow; H = white).
