Which of the following statements about $\beta$-sheet structures is true?
A) The individual strands of all $\beta$-sheet structures are connected by turns, helices, or loops.
B) All amino acid side chains in antiparallel and parallel $\beta$-sheet structures point to one side of the sheet.
C) Parallel $\beta$-sheet structures have backbone amides that directly hydrogen bond between strands, whereas antiparallel $\beta$-sheets have hydrogen bonds that are offset.
D) All $\beta$-sheet structures form a spiraling backbone chain.

The individual strands in beta-sheet structures (referred to here as F1F1F1S1βF1F1F10-sheet structures due to a formatting error) are indeed connected by various secondary structure elements such as turns, helices, or loops. This allows the protein to fold into its three-dimensional structure, facilitating the formation of the beta-sheet's characteristic pleated appearance.
