In terms of protein structure, what is a secondary structure, and which molecular bonds or interactions contribute to stabilizing this level of structure?

Secondary structure refers to the overall shape of the protein, such as the formation of the polypeptide fold. This level of structure is stabilized by noncovalent interactions between atoms in the backbone.

Secondary structure refers to the consistent arrangement of protein chain segments, such as the formation of an ɑ-helix or a β-sheet. This level of structure is stabilized by hydrogen bonding between atoms in the backbone.
