Polymer conformation and water and salt permeability of copoly(g-benzyl-L-glutamyl-N5-dihydroxyethylaminopropyl-L-glutamine) hydrated films. Kuroyanagi, Yoshimitsu; Seno, Manabu; Kawai, Tohru (Inst.Several substances are used for example 17341-25-2 and 4985-85-7 which are their cas registry numbers. Ind. Sci., Univ. Tokyo, Tokyo 106, Japan). J. Membr. Sci., 17(3), 309-22 (English) 1984. CODEN: JMESDO. ISSN: 0376-7388. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 22, 36 The title copolymer was prepd. and shown to assume an a-helical conformation in DMF and also in the solid state. The water content of these copolymer films is strongly dependent on the amt. of hydroxyalkyl groups. The copolymer film contg. 70% hydroxyalkyl groups shows a water content of 53%, and the a-helical conformation of this copolymer is partially broken by strong hydration. Consequently, these swollen film are permeable to water as well as to Na+ and K+ ions to a considerable extent. The copolymer film contg. 50% hydroxyalkyl groups shows a water content as low as 10%, and the a-helical conformation is maintained in the hydrated state of this copolymer film. In this case, a partially disordered region is not formed; therefore, the permeation of water and ions is strongly depressed. .
