Deamino Oxytocin and 1-γ-Mercaptobutyric Acid-Oxytocin: X-ray Crystallographic Data

Abstract
X-ray studies of crystalline deamino-oxytocin (1-β-mercaptopropionic acid-oxytocin) have established the existence of both wet and dry forms. A remarkable degree of similarity exists between the two forms even though there are changes in cell dimensions and space group on drying. The dry form of 1-γ-mercaptobutyric acid-oxytocin is very similar to that of deamino-oxytocin.
