Cystine peptides are conveniently prepared from S-acetamidomethyl- or S-trityl-protected cysteine derivatives by direct oxidation with iodine. Since the reaction proceeds through the formation of sulfenyl iodides, these highly reactive groups may sub

In 1979 the first abnormal human insulin was discovered. With the minute samples from the patient a Phe leads to Leu replacement could be established in either position B24 or B25. For the unequivocal localization of the substitution both the Leu ana

Previously reported studies of the iodine oxidation of S-trityl-cysteine peptides and S-acetamidomethyl-cysteine peptides, leading directly to cystine peptides, have been extended. Detailed investigations have been made of the reactivities of the S-t
