An important enzyme that bacteria use to break down urea is called urease. (We don't have the enzyme urease, but many bacteria do.) Since this enzyme interacts with urea (the structure of which is shown below), what type of intermolecular forces are involved in that interaction? (And how do you know?) H2N NH2
