The optical rotation and molecular configuration of synthetic polypeptides in dilute solution

Autor: W. E. Hanby, A. R. Downie, A. Elliott, B. R. Malcolm

Publikováno v: Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences. 242:325-340

The optical rotations of a number of synthetic polypeptides have been measured in a variety of solvents. For each polypeptide species, a number of copolymers of different D:L compositions have been examined. Several distinct types of behaviour have b

An examination of some physical properties of the α ll and β forms of three synthetic polypeptides (the 1:1 copolymer of DL- β -phenylalanine and DL-leucine, the 1:1 copolymer of DL- β -phenylalanine and L-leucine, and the 1:1:1 copolymer of DL-

The structure of synthetic polypeptides I. X-ray investigation

Autor: F. Happey, W. E. Hanby, C. H. Bamford

Publikováno v: Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences. 205:30-47

Oriented fibres and films of a number of synthetic polypeptides have been prepared, and examined by X-ray diffraction. It is shown that the polypeptides can exist in a folded ($\alpha $) and an extended ($\beta $) configuration. The observations on t

The near infra-red absorption spectra of natural and synthetic fibres

Autor: A Elliott, W E Hanby, B. R. Malcolm

Publikováno v: British Journal of Applied Physics. 5:377-381

The near infra-red region may be used to obtain spectra with polarized radiation of natural and synthetic fibres. This region has considerable experimental advantages and the spectra of poly-L-alanine, polyglycine, wool, silks and commercial regenera

Some new investigations on the structure of synthetic polypeptides

Autor: A. Elliott, C. H. Bamford, I. F. Trotter, L. Brown, W. E. Hanby

Publikováno v: Proceedings of the Royal Society of London. Series B - Biological Sciences. 141:49-59

Films of poly- γ -methyl-L-glutamate have been prepared with a high degree of orientation. X-ray photographs show that the least dimensions of the unit cell are a = 11·95 Å, b = 20·70 Å, c = 43·2 Å (fibre axis). One near-meridional reflexion,
