    Description: The C2 ungrouped Tagish Lake meteorite preserves a range of lithologies reflecting variable degrees of parent body aqueous alteration. Here we report on soluble organic compounds, including aliphatic and aromatic hydrocarbons, monocarboxylic acids and amino acids, found within specimens representative of the range of aqueous alteration. We find that differences in soluble organic compounds among the lithologies may be explained by oxidative, fluid-assisted alteration, involving changes from one type of soluble organic compound to another, or derivation of soluble organic compounds from macromolecular material. Our results demonstrate the role of parent body alteration in the modification of organic matter in the early Solar System, and have implications for interpretation of the complement of soluble organic compounds in carbonaceous chondrites.
