Question
Covalent bonds place constraints on the shapes of biological molecules. As the size and complexity of a biomolecule increases, the chemical focus shifts from covalent bonds to noncovalent interactions. Noncovalent interactions dictate the stable, native conformations of large macromolecules and polymers while permitting the flexibility necessary for their biological functions. What characteristics of weak noncovalent interactions enable the assembly, stability, and functions of biomolecules? They are transient, whereas covalent bonds tend to be long-lasting. They are not affected by the surrounding aqueous environment. They are stable, requiring a large amount of energy to break. They have a large aggregate strength when multiple interactions are present.Explanation / Answer
The main characteristics of weak noncovalent interactions which enable the assembly, stability and functions of biomolecules is that they are transient.They are involved in many biological processes in which large molecules bind specifically but transiently to one another.
