The hydrolysis of ascorbate-2-sulfate by the enzyme, ascorbate-2-sulfate sulfohydrolase, purified from bovine liver has been shown to be powerfully inhibited by ascorbate-2-phosphate. The inhibition by ascorbate phosphate is competitive with a KI of

The degradation of ascorbic acid by periodate has been studied using [1-14C] or [6-14C]ascorbic acid, as well as quantitative yield of the various products. Ascorbic acid, oxidized at pH 7.5 is cleaved to give 2 mol formate, 1 mol CO2, 1 mol of oxala

A new synthesis of l - threo -hex-2-enaro-1,4-lactone ( 4 ) (“saccharoascorbic acid”) is presented, whose unique feature involves oxidation of the side chain of ascorbic acid. Ascorbate 2-sulfate ( 1 ) was selectively oxidized in water at pH 8–

The distribution of the different kinetic classes of exchangeable hydrogens have been measured for γ-irradiated lysozyme (mucopeptide N -acetylmuramylhydrolase, EC 3.4.1.17). Class I hydrogen, associated with fully exposed structures, did not show s

SummaryA series of normal and tumor mice were injected with stilbamidine-amidine-C214. After 96 hours organs were removed and analyzed for radioactivity. Much higher and distinctly abnormal concentrations of C14 were found in the livers of tumor-bear
