General description

Sodium arsenate dibasic heptahydrate (As(V)) is an arsenic compound.

Application

Sodium arsenate dibasic heptahydrate may be used as a reference standard for the quantification of arsenic compounds in rice- and seafood-based samples by ion chromatography-inductively coupled plasma/ mass spectrometry. The samples for analysis were prepared by ultrasonic-assisted enzymatic extraction (UAEE).

Inorganic arsenic is a known human carcinogen, inducing tumors of the skin, urinary bladder and lung. It is metabolized to organic methylated arsenicals. 2,3-Dimercaptopropane-1-sulfonic acid (DMPS), a chelating agent, is capable of reducing pentavalent arsenicals to the trivalent state and

It has been suggested that arsenic (+3 oxidation state) methyltransferase (AS3MT) plays a critical role in methylation of arsenic, and that arsenic-glutathione conjugate is a substrate for AS3MT-catalyzed methylation of arsenic. However, the mechanism of arsenic methylation in cells is
