Being able to distinguish different types of macromolecules in a cell is a useful skill to have. Many times this can be achieved by synthesizing the molecule using an isotope of one of the types of atoms it contains (14C, 3H, 15N, 18O, 32P, 35S). Using your knowledge of the structure of the molecules below, determine the best atom to use for each. Make sure to
include which part of the molecule will be labeled and your reasons why this atom would uniquely identify each class of molecule.
