Astrobiology Analytical Laboratory


The Astrobiology Analytical Laboratory is dedicated to the study of organic compounds derived from sample return missions, meteorites, lab simulations of Mars, interstellar, proto-planetary, and cometary ices and grains, and instrument development.

This Chemical Reviews paper gives on overview of the distributions, enantiomeric ratios, and isotopic compositions of extraterrestrial amino acids and polyols that have been identified in meteorites compared to those found in terrestrial biology and synthesized under simulated prebiotic conditions. Drawn from these comparisons, a set of new measurement criteria for using chiral asymmetry as a biosignature are proposed for future life detection missions.
