REACTION OFN-p-TOSYLSULFILIMINE WITH TRIVALENT PHOSPHORUS COMPOUNDS

Reaction of Trivalent Organophosphorus Compounds with Selenium

Over the years, evidence has been accumulating [1, 2] that selenium is an essential nutrient in animals, preventing various serious deficiency diseases. On the other hand, no such firm proof for the need of selenium in human nutrition has been established, although several instances of beneficial effects as a result of selenium supplementation of human diet have been reported [3-5]. Although va...

Phosphorus Compounds in Animal Tissues

The concept that nucleic acids are intimately associated with fundamental cellular processes has gained considerable favor within the last few years. This can undoubtedly be attributed to the researches of Caspersson and his associates. Caspersson, with the aid of ultraviolet spectrophotometry, has been able to measure the nucleic acids in various parts of the cell under a variety of experiment...

Phosphorus Compounds in the Cell

In the first paper in this series (Davidson, Frazer & Hutchison, 1951) it was emphasized that in experiments on the incorporation of radioactive phosphorus (32p) into the nucleic acids and their derivatives in the cell, it was essential, in order to obtain true specific activities, to separate the nucleotide fractions in a form free from all traces of highly active contaminants. The procedure o...

Catalytic decomposition of phosphorus compounds to produce phosphorus atoms

Reaction of Pyo compounds with sodium hypoiodite.

It was noted early in the investigations of the Pyo compounds that treatment of Pyo I1 with an alkaline iodine solution resulted in the formation of a product which was markedly more active against Staphy1ococcu.s aureus than was the original substance. In t.hese cases, the activity of the product was about 10 times that of the starting material (1). Since it was known that this reagent has the...
