Question

The bond that determines the secondary structure of proteins
is
(a) coordinate bond (b) covalent bond
(c) hydrogen bond (d) peptide bond

Answer 1

Answer:

c

Explanation:

hydrogen bonding is the correct answer

Answer 2

It is the Hydrogen bond that determines the secondary structure of proteins.

• β-sheet and α helix are the secondary structures that exist for hydrogen bonding.

• Between the inter-strand of the β-sheet hydrogen bond can be seen.
• Coiled α helix structure contain N-H structure in which a hydrogen bond exist  and also has C=O structure where hydrogen bond exist between oxygen atoms.
