Question

which molecules retains the shape needed to be biologically active due to intermolecular forces?

Answer 1

proteins

Answer 2

a protein which is made up of one or more chains of amino acids fold after synthesis into a particular shape that maximizes favorable intermolecular interactions between the amino acid residues and the solvent it is in (water). The shape it forms assists it in its biological function. Remember a common theme in biology is structure dictates function

Answer 3

Well doesn't assist it but dictates its function
