For example, consider the two molecules in the picture to the right.
By conducting aspartic acid racemization measurements using an HPLC/fluorescence detection method, Bada analyzed the bowheads eye lenses to estimate the whales age at the time of death (2).The proteins in each lens nucleus were acid hydrolyzed into free amino acids, which were then derivatized.
