The broad latitudinal range of the sites provides a useful perspective on the relative kinetics
of racemization at substantially different temperatures.

Amino acid
racemization and the preservation
of ancient DNA.
Amino acids have the property
of being able to spontaneously flip from one form to another, a process called
racemization.
In soils, however, amino acids can be sequestered for thousands or even millions
of years, allowing
racemization to accumulate.
