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.

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.
Additionally, F I and F III had lowest metachromasy between extract and F II as supported the sulfate analysis (Table 1) due to a relatively lower degree of sulfation (ester sulfate groups, S = O) of the SPs (Rodrigues et al.
For instance, compositional analysis of GAG side chains isolated from malignant breast tissues indicate an elevation in CS expression, with an increase in CS-A and CS-E sulfation sequences and a decrease in CS-C and CS-D.
TABLE 2 Main CYP450 isoforms that metabolize statins and the azoles that inhibit them (6,7,10,19) CYP450 isoform Statin metabolized * Azole inhibitor (in order of decreasing potency) 3A4 Simvastatin; Ketoconazole, atorvastatin; itraconazole, lovastatin voriconazole, fluconazole 2C9 Fluvastatin; Voriconazole, rosuvastatin fluconazole, (minimal); ketoconazole pitavastatin (minimal) * Pravastatin is unique in that it is not metabolized by the CYP450 system, but through sulfation.
Phase 2 metabolism in human skin: skin explants show full coverage of glucuronidation, sulfation, n-acetylation, catechol methylation and glutathione conjugation.
Bioavailability of anthocyanins was extensively studied due to the different mechanisms of the uptake and metabolism (deconjugation, glucuronidation, sulfation, and deglucuronidation) in various cell lines.
Complex reactions then occur, including dissolution, sulfation, and sintering, ultimately leading to troublesome slagging and fouling deposits.
This study demonstrated that the metabolism of wedelolactone is glucuronidation or sulfation and the bioavailability of wedelolactone can be improved by other compounds present in WCE.
