Estimation of Chronological Age from the Racemization Rate of l- and d-Aspartic Acid: How to Completely Separate Enantiomers from Dentin

of technique. In general, living organs are composed of l -form amino acids. Conversion from l -form to d -form amino acids is a first-order chemical reaction. Thus, the quantity of d -form amino acids in an organ is proportional to the passed time (age
