Re: [meteorite-list] Meteorites with amino acids
Hi Rob and all! Nice list, Rob! Thanks! I've had the opportunity to work with several Jblit Winselwan fragments while making thin sections of them. It was obvious someone washed or rinsed a couple of the samples I had. In what, I do not know. Additionally, once the pieces came apart it was clear with both the none washed samples and the washed samples, terrestrial contamination occurred at some point in it's life on earth. All of them I have had reminded me of goat turds as to who they were formed and stuck togetheror a part of one that had already came apart. Very delicate material, but could be taken apart. So, I wonder what affect this would have on any amino acid study where strict handling protocol of the sample did not occur and what affect this would have on a study where terrestrial contamination is obvious. Would scientist still be able to isolate particles for studying amino acids and not be too concerned about contamination??? Have a great day!

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.

[meteorite-list] Meteorites with amino acids?
Hello, Does the Jbilet Winselwan (CM2) Meteorite contain amino acids like that of Murchison (CM2)? It's been awhile since I have studied meteorites, is Murchison still the only meteorite to contain amino acids? Last time I checked 93 amino acids had been found in the Murchison meteorite.

Hi Tim...not sure about Jbilet Winselwan...but they are found in others...eg Almahatta Sitta http://www.lpi.usra.edu/meetings/lpsc2010/pdf/1042.pdf Graham On Mon, Nov 17, 2014 at 9:41 AM, Tim Heitz via Meteorite-list meteorite-list@meteoritecentral.com wrote: Hello, Does the Jbilet Winselwan (CM2) Meteorite contain amino acids like that of Murchison (CM2)?
