Tertiary Structure of Protein Overview, Bonds

WebJul 3, 2024 · The tertiary structure is the final specific geometric shape that a protein assumes. This final shape is determined by a variety of bonding interactions between the “side chains” on the amino acids. These binding interactions may be stronger than the hydrogen bonds between amide groups holding the helical structure. WebSecondary structure is determined by Hydrogen bonds between the backbone of the chain. Tertiary structure is determined by all electrostatic interactions (e.g. H-bond, Van der Waals) as well as disulfide bridges. Quaternary structure is determined by the subunits and the attractions between the different subunits. jfk airport vip service
