“…However, with few exceptions (Gisler 1981;Whitehead 2003;Vlasova and Golovkova 2004;Vlasova 2005;Jonsson et al 2009). Most adsorption studies of amino acids on oxide surfaces have been limited to systems without control of pH and ionic strength (e.g., Holm et al 1983;Matrajt and Blanot 2004).…”

Crystalline surfaces of common rock-forming minerals are likely to have played several important roles in life's geochemical origins. Transition metal sulfides and oxides promote a variety of organic reactions, including nitrogen reduction, hydroformylation, amination, and Fischer-Tropsch-type synthesis. Fine-grained clay minerals and hydroxides facilitate lipid self-organization and condensation polymerization reactions, notably of RNA monomers. Surfaces of common rock-forming oxides, silicates, and carbonates select and concentrate specific amino acids, sugars, and other molecular species, while potentially enhancing their thermal stabilities. Chiral surfaces of these minerals also have been shown to separate left-and right-handed molecules. Thus, mineral surfaces may have contributed centrally to the linked prebiotic problems of containment and organization by promoting the transition from a dilute prebiotic "soup" to highly ordered local domains of key biomolecules.

“…They have stood in the snow and later in the well for the same amount of time as the MMs, and were recovered at the same time and under the same conditions. They were called rust grains and were chosen instead of any other kind of particles because iron oxides have been shown to well adsorb inorganic and organic compounds (Cornell and Schwertmann 1996), in particular amino acids (Holm et al 1983;Matrajt et al 2003). We think, therefore, that these particles represent the best blank, because they were subjected to the same environmental and experimental conditions as the MMs were.…”

Abstract-Micrometeorites (MMs) are extraterrestrial particles ranging in size from 25 µm to 2 mm that survive atmospheric entry and are collected on the Earth's surface. They represent the largest mass flux (MF) of extraterrestrial material (30,000 ± 20,000 t/yr) to the present-day Earth. Studies of large collections of MMs suggest that about 20% have not been heated to high temperatures and that they contain organic carbon. Since non-protein amino acids have been found in some carbonaceous meteorites, they might also be found in unmelted MMs. However, previous searches for amino acids in MMs were inconclusive. We combined a new extraction method for amino acids with a highly sensitive analytical method to detect and quantitate amino acids in MMs collected at the South Pole. We found the non-protein amino acid α-amino isobutyric acid (AIB) in one of our samples. The nondetection of this amino acid in the other samples analyzed suggests that there are amino acidcontaining and amino acid-free MMs, with ∼14% of the MMs containing AIB. Since the MF of MMs is much higher than that of carbonaceous chondrites (CMs), amino acids in these small particles would represent an important source of exogenous delivery of organic molecules. Therefore, the results are discussed on the basis of their implications for astrobiology.
