International Journal of Chemical Kinetics. These have produced models of protein adhesive and other biopolymer deteriorations and the concurrent pore system development. Amino acid racemization also has a role in tissue and protein degradation studies, particularly useful in developing museum preservation methods. Sample preparation entails the identification, raw extraction, and separation of proteins into their constituent amino acids, typically by grinding followed by acid hydrolysis. The differentiation of cooked from uncooked bone, shell, and residue is sometimes possible.

This includes racemization rate variation among species and organs, and is affected by the depth of decomposition, porosity, and catalytic effects of local metals and minerals. Verification of radiocarbon and other dating techniques by amino acid racemization and vice versa has occurred. The enclosing matrix is probably the most difficult variable in amino acid dating. These are important for amino acid dating because racemization occurs much faster in warm, wet conditions compared to cold, dry conditions.
