Genetic Code Table: A note on the three splittings into amino acid classes [PDF]

open access: yesarXiv, 2009
This note represents the further progress in understanding the determination of the genetic code by Golden mean (Rakocevic, 1998). Three classes of amino acids that follow from this determination (the 7 "golden" amino acids, 7 of their complements, and 6 non-complements) are observed now together with two further possible splittings into 4 x 5 and 5 x ...

Highly sensitive analysis of sterol profiles in human serum by LC-ESI-MS/MSs⃞

open access: yesJournal of Lipid Research, 2008
We have developed a highly sensitive and specific method for the analysis of serum sterol profiles. Sterols in 1 μl of dried serum were derivatized into picolinyl esters (3β-picolinate) and analyzed by liquid chromatography-tandem mass spectrometry (LC ...

Indigenous amino acids in primitive CR meteorites [PDF]

open access: yesarXiv, 2008
CR meteorites are among the most primitive meteorites. In this paper, we report the first measurements of amino acids in Antarctic CR meteorites, two of which show the highest amino acid concentrations ever found in a chondrite. EET92042, GRA95229 and GRO95577 were analyzed for their amino acid content using high performance liquid chromatography with ...
