|Most amino acids can have two different configurations, "D" or "L". Living organisms generally have amino acids in the "L" configuration, but when the organism dies, the ratio of D/L moves slowly toward equilibrium, a process called racemization. Measuring the ratio of D/L in a geologic sample containing preserved amino acids can therefore allow calculations of the age of the sample.|
