The primary structure is held together by covalent peptide bonds. … Among these forces, the non-specific hydrophobic interaction is the main force driving the folding of protein, while hydrogen bonds and disulfide bonds are responsible for maintaining the stable structure.

What bonds support the primary protein structure?

What type of bonds are found in the primary structure of a protein? Explanation: Primary structure consists of amino acids joined by peptide bonds. Peptide bonds are between the alpha-carboxyl of one amino acid, and the alpha-amine of the next amino acid.

Why are primary protein structures stable?

Hydrogen bonds form between the oxygen of each C=O. bond in the strand and the hydrogen of each N-H group four amino acids below it in the helix. The hydrogen bonds make this structure especially stable. The side-chain substituents of the amino acids fit in beside the N-H groups.
