Abstract

Abstract The thiols 4-mercapto-4-methylpentan-2-ol (4MMPOH), 3-mercaptohexan-1-ol (3MH), and 3-mercaptohexyl acetate (3MHA), which contribute to the aroma profile of Sauvignon Blanc, as well as other varieties of wine, have been synthesized with deuterium labels. The cysteinylated precursors of the thiols, 4-(4-methylpentan-2-one)-L-cysteine (4MMP-cys) and 4-(4-methylpentan-2-ol)-L-cysteine (4MMPOH-cys), found in grape must ...
