| Abstract: | The extent of racemization of aspartic acid (Asp) – expressed as d/l ratio – has been used as a marker of biomolecular degradation in ancient remains. However, Asp racemization rate is highly variable, and depends on biochemical and geochemical factors. In this paper we aim to determine to which extent the fraction analyzed and the kind of sample used may influence the d/l Asp ratios. Other factors, such as burial site and sample preservation conditions, are also considered. |
