Circular dichroism spectra of N,N-Dimethyl-L-amino acids

Abstract

The circular dichroism spectra in the region 190-300 nm have been measured at pH 1 and pH 13 in aqueous solution for a series of N,N-dimethyl-L-amino acids. A dominant positive Cotton effect is generally observed between 205 and 225 nm as has been found previously for the parent L-amino acids. These results are consistent with the same conformer being dominant for both series of compounds.
