Analysis of amino acids, hydroxy acids, and amines in CR chondrites.

ABSTRACT: The abundances, relative distributions, and enantiomeric and isotopic compositions of amines, amino acids, and hydroxy acids in Miller Range (MIL) 090001 and MIL 090657 meteorites were determined. Chiral distributions and isotopic compositions confirmed that most of the compounds detected were indigenous to the meteorites and not the result of terrestrial contamination. Combined with data in the literature, suites of these compounds have now been analyzed in a set of six CR chondrites, spanning aqueous alteration types 2.0-2.8. Amino acid abundances ranged from 17 to 3300 nmol g^-1 across the six CRs; hydroxy acid abundances ranged from 180 to 1800 nmol g^-1; and amine abundances ranged from 40 to 2100 nmol g^-1. For amino acids and amines, the weakly altered
