Why is cellulose so difficult for most animals to digest?
a) they don’t have the proper enzyme to break the bonds between subunits
b) cellulose is made up of chitin, which is indigestible
c) the bonds holding cellulose subunits together are extremely strong, stronger than in any other macromolecule
d) there are many hydrogen bonds holding the subunits together

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
