Primary protein structure is dependent on

E) all of these.

Question

Quizplus · Accepted Answer

Primary protein structure refers to the linear sequence of amino acids in a protein. This sequence is determined by peptide bonds, which are covalent linkages between the carbon and nitrogen atoms of adjacent amino acids. Therefore, primary protein structure is dependent on covalent linkages between carbons and nitrogens of adjacent amino acids. Hydrophobic interactions and hydrogen bonds between two amino acids play a role in determining secondary and tertiary protein structure, while covalent linkages between carbons and oxygens of adjacent amino acids form ester bonds in lipids, not proteins.
