Question

Quizplus · Accepted Answer

Urea disrupts non-covalent interactions, such as hydrogen bonds and ionic interactions, but does not affect peptide bonds, which are covalent. Therefore, the protein will retain its peptide bonds when placed in urea. Choices B and C relate to the secondary structure of proteins, which are stabilized by non-covalent interactions, and are therefore disrupted by urea. Choices D and E also relate to non-covalent interactions and are therefore also disrupted by urea.
