Sulfur isotope fractionation during incorporation of sulfur nucleophiles into organic compounds.
(34)S enrichment is shown to occur during sulfurization reactions and for the first time conclusively attributed to an isotope equilibrium effect rather than selective addition of (34)S enriched nucleophiles.
متن کاملProduction of volatile organic sulfur compounds (VOSCs) by basidiomycetous yeasts.
Thirty-seven basidiomycetous yeasts belonging to 30 species of seven genera were grown on media containing l-cysteine or l-methionine as sole nitrogen sources with the objective of evaluating volatile organic sulfur compound (VOSC) production. The headspace of yeast cultures was analyzed by the solid-phase microextraction (SPME) sampling method, and volatile compounds were quantified and identi...
متن کاملThe Organosulfur Chemistry of the Genus AZZium - Implications for the Organic Chemistry of Sulfur
A Cook’s tour is presented of the organosulfur chemistry of the genus Allium, as represented, inter alia, by garlic (Allium sativum L.) and onion (Allium cepa L.). We report on the biosynthesis of the S-alk(en)yl-L-cysteine S-oxides (aroma and flavor precursors) in intact plants and on how upon cutting or crushing the plants these precursors are cleaved by allinase enzymes, giving sulfenic acid...

(tetrahydrofuran) at 703C for 16 h. The ester residue is then converted to a 6,6-dideuteriohexose residue, the O-methyl ethers of which are easily distinguishable by GC-MS of the derived alditol acetates. An alternative to acid hydrolysis that is applicable to most polysaccharides and glycoconjugates, including those containing acid-labile residues or glycosidic linkages resistant to hydrolysis...
متن کاملVolatile organic compounds: a bacterial contribution to plant sulfur nutrition.
In the decade since it was first reported that volatile organic compounds (VOCs) released by bacteria can promote plant growth, it has become clear that VOC-mediated interactions between bacteria and plants are widespread (reviewed in Bailly and Weisskopf, 2012). The effects of VOCs on plants have been found to vary, ranging from plant growth promotion to inhibition, even within the same combin...
