Phosphoric esters of the pancreas: choline glycerophosphate

Glycerylphosphorylcholine and choline glycerophosphate.

In 1938-9 at the British Postgraduate Medical School, King & Aloisi isolated from dried pancreas a glycerophosphoric ester of choline which was found to be readily hydrolyzable. Evidence was also obtained for the existence of a dicholine ester. This work was published only in 1945 owing to war difficulties. In the same year Schmidt, Hershman & Thanmhauser (1945) reported the isolation of aglyce...

Phosphoric Esters of Biological Importance

A metabolic pathway by which glucose, fructose, and mannose are metabolized in mammalian tissue has been elucidated. This is not the case, however, for galactose, a sugar whose metabolic significance is evinced by the fact that it provides half of the dietary supply of carbohydrate for most young mammals and is usually present in the diet of man throughout his life. Galactose is converted to ga...

Phytin and Phosphoric Acid Esters of Inosite

In continuation of the physiological investigation concerning the metabolism of the organic-phosphorus compound known as phytin, which has been and is being carried out at this institution by Dr. Jordan, a closer study of the chemical properties of this substance, phytin, became necessary. Much work has already been done and reported on this subject by various investigators. Definite informatio...

Systems for the separation of phosphoric esters by solvent distribution.

The isolation and purification of phosphoric esters are usually accomplished by the fractional precipitation of their metallic salts. This method has been extremely useful and has led to the isolation of a large number of biologically important phosphorus compounds. However, some types of compounds are merely separated by this procedure into groups from which the individual members cannot be re...
