Comments P.14 top paragraph:"For example, the Murchison meteorite contains about 2% by weight organic matter, most of which is insoluble macromolecular material (polyaromatic hydrocarbons, which are nonfermentable) accompanied by 23 different classes of organic compounds, each class present at only ppm (parts per million) levels, the most common class being monocarboxylic acids, present in various chain lengths and as various isomers [primary source]." Wiki:"The Murchison meteorite is named after Murchison, Victoria, in Australia. It is one of the most studied meteorites due to its large mass (>100 kg), the fact that it was an observed fall, and that it belongs to a group of meteorites rich in organic compounds."
