A weak force of attraction between molecules that is important in biological molecules is known as non covalent interaction.

Explanation:

Noncovalent Interaction is one of the most important interaction that in present in the chemical structure of various macromolecules such as protein,lipid,nucleic acid etc.

           The non covalent interaction involves

Hydrogen bonding that helps to stabilize the structure of proteins and nucleic acids.

vanderwaal interaction helps to stabilizes the structure of nucleic acids.

Hydrophobic interaction helps to stabilizes the structure of lipid molecules and nucleic acids.
