Question

In proteins, which of the following are the characteristic patterns that arise when hydrogen bonds form between amino acids?

A. Quaternary structure.

B. Tertiary structure

C. Primary structure

D. Secondary structure

Answer 1

Proteins have four levels of organization. Primary structure refers to the linear sequence of the amino acids connected by the peptide bonds. The secondary structure consists of local packing of polypeptide chain into α-helices and β-sheets due to hydrogen bonds between peptide bond – central carbon backbone.
