sulfation

[səl′fā·shən]
(chemistry)
The conversion of a compound into a sulfate by the oxidation of sulfur, as in sodium sulfide, Na2S, oxidized to sodium sulfate, Na2SO4; or the addition of a sulfate group, as in the reaction of sodium and sulfuric acid to form Na2SO4.

While sulfation over time limits the number of charge/discharge cycles a battery can survive, insufficient charging during normal operation will also cause sulfation, shortening the useful life of the battery.
Based on cDNA cloning experiments, we demonstrated that PSK is produced from an approximately 80 amino acid precursor polypeptide via tyrosine sulfation and proteolytic processing.(24),(25) Five paralogous PSK genes are present in the Arabidopsis genome.
In addition, lifetime exposure of bipolar patients to lithium is associated with an increase in PNN sulfation patterns that render the nets more sensitive to proteolytic digestion [117].

When administered early after an acute APAP overdose, NAC provides cysteine for the replenishment and maintenance of hepatic glutathione stores, enhances the sulfation pathway of elimination, and may directly reduce NAPQI back to acetaminophen [31, 32].
The impact of sulfur on metal zeolite catalysts were evaluated by analyzing NOx reduction, NO oxidation, N[H.sub.3] oxidation, and N[H.sub.3] storage before and after sulfation.

Second, and very fortunately, not all sulphur amino acids in the diet are excreted, since they supply sulphur that is used to create glutathione and function in many important enzymatic pathways such as sulfation.
