"Sulfur has been the preferred spelling of the International Union of Pure and Applied Chemistry (IUPAC) since 1990, and is also preferred by many scientific journals and Radiopaedia 2. The alternative spelling sulphur may still be found in common use in the UK and Commonwealth, especially by laypeople. By extension all sulfur-derived compounds are also spelt using the 'f' form e.g. sulfuric acid, disulfite etc. "Thiol" refers to a specific chemical side group containing sulfur."
"The daily dietary requirement of sulfur-containing amino-acids (SAAs) is recommended as ~13–15 mg/Kg 5. The majority of this is as the compound cystine, a disulfide oxidised derivative of cysteine."
"Although sulfur has been known since ancient times, the renowned French chemist Antoine Laurent Lavoisier (1743-1794) 4 was the first person to realise that sulfur was a chemical element in 1777. Unfortunately he met a rather premature end under the guillotine during the French revolution."

"Sulfur is generally stored in the cells as the oligopeptide glutathione (GSH). Cysteine and methionine are not stored by the body, and if there is an excess they pass into the urine, are oxidised to sulfate or metabolised to glutathione to be stored 6."
"Methionine is metabolised to homocysteine, and via the transsulfuration pathway to cysteine. Cysteine is a precursor for the synthesis of glutathione (GSH), a key tripeptide intracellular redox agent neutralising free radicals and toxins, and acting as an enzymatic cofactor."
"Several important food sources for sulfur are garlic, onions, and other vegetables, which are rich in sulfur-containing compounds, e.g. isothiocyanates, diallyl sulfide and allicin."
"Sulfur is used in nuclear medicine in the synthesis of sulfur-colloid compounds. Eight atoms of sulfur are arranged in a ring, with the IUPAC name of octathiocane, and complexed with a single technetium atom (formula: S8Tc) 8."

"There are four stable isotopes of sulfur, which are S-32, S-33, S-34 and S-36. Sulfur-32 accounts for 95% of the element on earth, with sulfur-34 accounting for most of the rest. Twenty other unstable isotopes of sulfur are known to exist, most with short half lives ("
"Absorption, transport and storage"
"As dietary sulfur is not consumed in the elemental form, excessive or deficient elementary sulfur is not generally an issue. However toxic intakes of both methionine or cysteine/cystine are well-recognised with potentially marked deleterious effects, e.g. on brain development 6."
