摘要：

Extending CD spectroscopy: Strong circular dichroic (CD) transitions in amino acids were observed when CD spectroscopy was extended to the vacuum-ultraviolet spectral range between 140 and 190 nm (see picture). Here, proteinogenic amino acids show the same CD magnitude and the same sign, and circularly polarized light is thus capable of inducing enantiomeric excesses of the same handedness. Interestingly, typical "meteoritic" amino acids have different CD properties. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
