Chemical Properties of S—S Groups and Methods for Their Scission
Valuable information on the spatial structure of cystine has been obtained by x-ray analysis of crystals of N, N’-diglycyl-L-cystine dihydrate. The geometry of the molecule of this disulfide is shown in Fig. 3, which shows that the dihedral angle between the two C—S bonds of the disulfide is 101° and that the length of the sulfur-sulfur bond is 2.04 Å. Similar data were obtained on X-ray crystallographic analysis of L-cystine hydrochloride (Steinrauf et al., 1958).
