Thiocyanate and chloride as competing substrates for myeloperoxidase.
The neutrophil enzyme myeloperoxidase uses H2O2 to oxidize chloride, bromide, iodide and thiocyanate to their respective hypohalous acids. Chloride is considered to be the physiological substrate. However, a detailed kinetic study of its substrate preference has not been undertaken. Our aim was to establish whether myeloperoxidase oxidizes thiocyanate in the presence of chloride at physiologica...
متن کاملA direct photometric method for chloride in biological fluids, employing mercuric thiocyanate and perchloric acid.
The reagent described is 5.5 M in perchioric acid and 3.3 M in urea. It contains ferric ions, mercuric thiocyanate, mercuric ions (from mercuric perchiorate), and mercuric chloride. Serum dissolves directly in this reagent to yield a clear, reddish solution. When chloride ions are added, they combine first with the free mercuric ions, and then with some of the mercuric ions from the mercuric th...
متن کاملStudies on Goitrogenic/ Antithyroidal Potentiality of Thiocyanate, Catechin and After Concomitant Exposure of Thiocyanate-Catechin
In adequate iodine intake including and a number of environmental agents can affect thyroid gland functions in man and animals. Thiocyanate and catechin that arise for the consumption of cyanogenic and flavonoids containing foods respectively, affect thyroid hormone synthesis but the data comparing the goitrogenic/ antithyroid potentiality of thiocyanate and catechin when act individually or sy...
متن کاملThe Binding of Thiocyanate to Albumin
Since the report of Crandall and Anderson (1) in 1934, the distribution of thiocyanate ion in the body has been used as a measure of extracellular fluid volume. All such work has been based on the procedure of administering a known amount of a thiocyanate, and after an interval, measuring the concentration of thiocyanate in the serum. The amount of thiocyanate injected, or more accurately, the ...
متن کاملThe combination of insulin with thiocyanate ions.
Measurements of the electrophoretic mobilities of insulin reported by Hall (1, 2) are limited to regions higher than pH 7 and lower than pH 4.5, since the protein is practically insoluble in common buffer solutions of the intermediate pH range. While it has been possible to determine the elect.rophoretic mobility of adsorbed insulin and of suspensions of insulin crystals in the isoelectric rang...
