Katsu, Rob, Tim and List,

Table 1 A summary of total amino acid and nucleobase data for five
of the eight carbonaceous chondrite groups. Amino acid and nucleobase
analyses of CI, CH, CB, and CK meteorites have not yet been reported

Amino acids have also been studied in CR2s, CR3s, CO3s and CV3s CIs and other types of meteorites.

Meteorite classification
Example - Meteorite
Predominant alteration type
Amino acids ppm
Nucleobases ppb

CR2 EET 92042 Aqueous 300ppm less than 25ppb

CO3 ALHA 77307 Thermal =1ppm no data
CV3 EET 96026 Thermal =1ppm no data---

List of amino acids given in paper.

References cited show many more meteorites and types studied and their names.

Amino acids have been found in the following meteorites of which I'm aware:

Murray (CM2)
Murchison (CM2)
Tagish Lake (C2 ungrouped)
Almahata Sitta (anomalous ureilite)
Sutter's Mill (CM2)
Allan Hills 77306 (CM2)
Allan Hills 83100 (CM2)
Asuka 88120 (CM2)
Asuka 881334 (CM2)
Lewis Cliffs 90500 (CM2)
Lone Wolf Nunataks 94102 (CM2)
Yamato 74662 (CM2)
Yamato 791198 (CM2) - most amino-acid-rich meteorite known
Yamato 793321 (CM2)
Belgica 7904 (CM2)
Orgueil (CI1)
Ivuna (CI1)

I am sure there are others that I have missed. --Rob
