Answer #1

The proteins have different levels of structure. These are primary, secondary, tertiary, and quaternary. The secondary structures arise to the formation of hydrogen bonds between the Hydrogen of N-H groups and O of the C=O group.

There are two major secondary structures and these are alpha-helices and beta-sheets. Alpha-helices form a coiled structure while beta-sheets, as the name suggests, form a linear structure of parallel, anti-parallel or mixed beta-sheets.

The alpha-helices only have inter-strand hydrogen bonds as a result, they have the ability to extend and bend. On the other hand, beta-sheets are formed by inter-chain hydrogen bonds. Therefore, there are more constraints present in the beta-sheets that hinder their geometry in space.

Hence, the answer is True.
