X‐Rays and the Stoichiometry of the Proteins

Osborne's work on the preparation of proteins was completed long before the development of the ph sical-chemical theory of acidity and the concept of solubility as a function of ionic strength. Nevertheless, his experimental handling of these factors, although empirical, was masterly.* Present-day methods show that casein yields about 22 per cent of glutamic acid. On the other hand, it is not impossible that Hlasiwetr and Habermann calculated the yield as glutamic acid hydrochloride, in which case they were not very much in error. Nevertheless, later research has shown that it is difficult to isolate more than half of the glutamic acid of casein by the method they used.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
