Amino-Acid Racemization Dating of Fossil Bones, Bada, Jeffrey

The racemization of L-isoleucine to D-alloisoleucine is, therefore, of special interest in the amino acid racemization dating system. Since the amino acids in proteins of living things are of the L-form, but upon death of the plant or animal spontaneously tend to change to mixtures of the L- and D-forms, the extent of this racemization process.
