Amino and Fatty Acids in Carbonaceous Meteorites
The presence of organic substances in carbonaceous meteorites has been known for at least one hundred and forty years. In 1834, for example, Berzelius (1) extracted complex organic substances from the Alais meteorite, and speculated about the significance of his discovery and its relationship to the possibility of extraterrestrial life. Since that time many studies of the organic chemistry of meteorites have been undertaken (2), and during this period controversies have developed concerning whether the organic material was a product of some extraterrestrial life. Within the last few years, however, new discoveries have narrowed the speculation. It is now generally believed that the indigenous organic compounds in meteorites are not derived from an extraterrestrial biota, but rather have been produced extraterrestrially by non- biological, chemical syntheses (3-8). In fact, these recent discoveries have provided persuasive, naturally occurring evidence in strong support of the theory of chemical evolution as first proposed by A. I. Oparin (9) in 1924.
