In studying a particular biomolecule (a protein, nucleic acid,
carbohydrate, or lipid) in the laboratory, the biochemist first
needs to separate it from other biomolecules in the sample (that
is, it needs to be purified). Specific purification techniques are
described later in the text. However, by looking at the monomeric
subunits and functional groups of a biomolecule, you should have
some ideas about the characteristics of the molecule that would
allow you to separate it from other molecules. Look for...
