[edit] Amino Acid List
I just removed the following list of amino acids found in the meteorite from the Amino acid page:
Amino Alkanoic Acids 2 Carbon: Glycine 3 Carbon: Alanine b-alanine Serine Sarcosine 4 Carbon: Threonine a-Aminobutyric Acid b-Aminobutyric Acid g-Aminobutyric Acid a-Aminoisobutyric Acid b-Aminoisobutyric Acid N-EthylglycineN,N-dimethylglycine N-Methylalanine N-methyl-b-alanine 5 Carbon: Valine Isovaline Norvaline Proline Methionine 3-Amino-2-ethylpropanoic Acid 3-Amino-2,2-dimethylpropanoic Acid 3-Amino-2-methylbutanoic Acid 3-Amino-3-methylbutanoic Acid 4-Amino-2-methylbutanoic Acid 4-Amino-3-methylbutanoic Acid Allo-3-amino-2-methylbutanoic Acid 3-Aminopentanoic Acid 4-Aminopentanoic Acid 5-Aminopentanoic Acid Amino Dialkanoic Acids 4 Carbon: Aspartic Acid 5 Carbon: Glutamic Acid 2-Methylaspartic Acid 3-Methylaspartic Acid Allo-3-methylaspartic Acid N-Methylaspartic Acid 6 Carbon: a-Aminoadipic Acid 2-Methylglutamic Acid 7 Carbon: a-Aminopimelic Acid Amino Alkanoic Acids 6 Carbon: Leucine Isoleucine Alloisoleucine Norleucine Pseudoleucine Cycloleucine 2-Methyl-norvaline Pipecolic Acid 2-Amino-2-ethylbutanoic Acid 3-Amino-2-ethylbutanoic Acid* 2-Amino-2,3-dimethylbutanoic Acid 3-Amino-2,3-dimethylbutanoic Acid* 4-Amino-3,3-dimethylbutanoic Acid* 3-Amino-3-methylpentanoic Acid* 4-Amino-2-methylpentanoic Acid* 4-Amino-3-methylpentanoic Acid* 4-Amino-4-methylpentaoic Acid* 3-methylamine-pentanoic Acid* 4-Aminohexanoic Acid* 7 Carbon: 2-Amino-2,3,3-trimethylbutanoic Acid 2-Amino-2-ethyl-3-methylbutanoic Acid 2-Amino-2-ethylpentanoic Acid 2-Amino-3-ethylpentanoic Acid 2-Amino-2,3-dimethylpentanoic Acid 2-Amino-2,4-dimethylpentanoic Acid 2-Amino-3,3-dimethylpentanoic Acid 2-Amino-3,4-dimethylpentanoic Acid 2-Amino-4,4-dimethylpentanoic Acid Allo-2-amino-2,3-dimethylpentanoic Acid* Allo-2-amino-3,4-dimethylpentanoic Acid 2-Amino-2-methylhexanoic Acid 2-Amino-3-methylhexanoic Acid 2-Amino-4-methylhexanoic Acid 2-Amino-5-methylhexanoic Acid Allo-2-amino-3-methylhexanoic Acid* Allo-2-amino-4-methylhexanoic Acid* 2-Aminoheptanoic Acid 8 Carbon: An amino alkanoic acid* 9 Carbon: Phenylalanine Tyrosine D- and L-2,3-diaminopropanoic acid D- and L-2,4-diaminobutanoic acid 3,3'-diaminoisobutanoic acid 2,3-diaminobutanoic acid 4,4'-diaminoisopentanoic acid
Such detailed info about one specific specimen seems inappropriate for the general amino acid page, and someone reading about the meteorite itself would likely not see it there either. Someone who is interested should consider adding it here, formatting it as a wiki list (or list of sublists, or whatever), adding italics, greek letters, caps/lowercase and other standard chemical typographic conventions, etc. DMacks 18:06, 5 June 2006 (UTC)
[edit] Non-linear catalysis
is this paragraph a joke? i hope so: "The catalysis is non-linear, that is proline with an enantiomeric excess of 20% yields a allose with enantiomeric excess of 55% starting from a benzyloxy acetaldehyde in a sequential aldol type reaction in an organic solvent like DMF [5]. In other words a small amount of chiral amino acids may explain the evolution of right-handedness of sugars." —The preceding unsigned comment was added by 143.252.80.100 (talk • contribs) 13:31, 27 July 2006 (UTC).
Are you questioning the science of the amplification (20% leads to 55%), something else about the science, the relevance to the meteorite, or something else? DMacks 14:51, 27 July 2006 (UTC)
