Explanation / Answer

A).Strands of proteins or peptides have distinct characteristic local structural conformations called secondary structure which is dependent on hydrogen bonding. The two main types of secondary structure are the -helix and the ß-sheet.

-helix is a right-handed coiled strand.Hydrogen bonds form between the oxygen of the C=O and the hydrogen of the N-H group. The hydrogen bonds make this structure especially stable.

The hydrogen bonding in a ß-sheet is between strands (inter-strand) rather than within strands (intra-strand). The carbonyl oxygens in one strand hydrogen bond with the amino hydrogens of the adjacent strand.
