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...

Reaction of Allicin-related Compounds with Protein.

protein in vitro and also with body constituents in vivo. They assumed that allicin was not chemically bound with the SH groups of protein, but it was additionally bound forming a complex. Allicin was not liberated from the "com plex" by washing with water or saturated ammonium sulfate solution, but could be easily separated by extracting with ethanol in which allicin is easily soluble. When pr...

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...
