Introduction: Previous work on this subject Figureau et al conducted a series of experiments to test the validity of Salam prediction. They observed no changes of optical rotation in solution after exposing both racemic DL cystine and L-cystine to temperatures ranging from 77K to 0. 6K for three and four days, thus reported failing to validate PVED-induced phase transitions predicted by salam Figureau, A, Duval, E; Boukenter, A.
