Characterization of polysulfides in Saccharomyces cerevisiae cells and finished wine from a cysteine-supplemented model grape medium

Untargeted polysulfide omics analysis of alternations in polysulfide production during the germination of broccoli sprouts

“…It is well established that GS n G ( n = 3–5) is endogenously produced in various living organisms, including humans, mice, and yeast [ 9 , [34] , [35] , [36] , [37] ]; however, little is known about this process in plants. To detect the endogenous production of GS n G, the broccoli seeds and sprouts were homogenized in the presence of TME-IAM, which can convert hydropolysulfides into a stable adduct without artificial decomposition due to its iodoacetyl group and can stabilize the polysulfide structure by inhibiting hydrolysis due to its hydroxyphenyl group, resulting in the minimized artificial formation of the oxidized derivatives of polysulfides during sample preparation [ 19 ].…”
