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...

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...

Chemical pathways of epoxidized and hydroxylated fatty acid methyl esters and triglycerides with phosphoric acid†

The polymerization pathways of epoxidized and hydroxylated triglycerides with phosphoric acid (H3PO4) were investigated using model reactions. Involved epoxides and diols were derived from oleic acid methyl ester, which was easily monitored by oneand two-dimensional nuclear magnetic resonance (NMR) techniques as well as electrospray ionization mass spectroscopy (ESI-MS). Phosphoric acid played ...

Dissociative electron attachment to phosphoric acid esters: the direct mechanism for single strand breaks in DNA.

We use dibutyl phosphate to simulate the behavior of the phosphate group in DNA towards the attack of low energy electrons. We find that the compound undergoes effective dissociative electron attachment within a low energy resonant feature at 1 eV and a further resonance peaking at 8 eV. The dissociative electron attachment (DEA) reactions are associated with the direct cleavage of the C-O and ...
