## Abstract The effects of three cationic surfactants, dodecylammonium chloride (DAC), dodecyldimethylammonium chloride (DDAC), and dodecyldimethylammonium chloride (DTDAC), on the conformation of poly(Lβglutamic acid) and at neutral pH were examined by CD. The maximum extent of the Ξ±βhelix inducti
The binding of the methylmercury cation CH3Hg+ by poly(L-glutamic acid) (PGA) and by poly(i-lysine) (PLL) has been investigated by b a n spectroscopy. Coordination on the side-chain COO-and NH; groups of these polypeptides gave characteristic ligand-Hg stretching modes at ca. 505 and 450 cm-', respe
## Abstract Pinacyanol in the presence of an excess of poly(Lβglutamic acid) [polymer/dye ratio (__P__/__D__) > 10] exhibits different absorption spectra in the visible region when bound to the slightly charged polypeptide in the Ξ±βhelical conformation or to the nearly completely dissociated polype
