Which bonds are created during the formation of the primary structure of a protein?

peptide bonds are created during the formation of the primary structure

Explanation:

The primary structure of a protein is the amino acids sequence of a protein or polypeptide chain, is the linear sequence of the protein . The amino acids are joined by peptide bond or amide bonds, this is the reason of the name polypeptide.

Carboxylic acid and an amino group form the peptide bond by the loss of a water molecule. The peptide bond is a covalent bond. It forms a relatively rigid unit. It´s synthesis is an enzymatically process carried out and controlled by the ribosome.

The characters of the peptide bond have influence on the flexibility and stability of polypeptide
