The primary structure of a protein is determined by_________ .

Question

Quizplus · Accepted Answer

The primary structure of a protein is determined by the sequence of amino acids. This sequence is held together by covalent bonds, known as peptide bonds. Hydrogen bonds may play a role in the secondary and tertiary structure of a protein, along with pleated sheets and helical domains, but they do not determine the primary structure. Fibroin is a protein found in silk, so covalent bonds formed between fibroin residues would not apply to all proteins.
