Web6 apr. 2013 · The ionic bonds are weak bonds resulting from the attraction between two oppositely charged polar groups. It formed between the carboxyl group and an amino group of an amino acid molecule. These connections can be made within the same chain, the polypeptide folding.

WebIn addition to the hydrogen bonds, ionic bonds between the charged groups also play a role in stabilizing beta-bends. Super secondary structures In making globular proteins like myoglobin, hemoglobin, etc., multiple secondary structures are combined resulting in the formation of specific geometric patterns called super secondary structures or motifs. WebThis is known as the tertiary structure, or commonly reffered to as the 3D conformation of the protein.
