Bonded interactions

Definition

Bonded interactions refer to the forces that hold atoms together within molecules, primarily through covalent bonds, which involve the sharing of electron pairs between atoms. These interactions are crucial in determining the stability and structure of biomolecules such as proteins and nucleic acids, which are essential for biological function. Understanding these interactions is vital in protein folding simulations, as they influence how proteins achieve their functional conformations.
