title: [Thermal decomposition of cysteine, cystine, N-acetylcysteine, 4-thiazolidinecarboxylic acid and cysteine methyl ester in soy bean oil (authors transl)].
abstract: During the thermal decomposition of cysteine, cystine, N-acetylcysteine, 4-thiazolidinecarboxylic acid, cysteine methyl ester, in soy bean oil at 200 degrees C, a series of compounds containing sulphur are formed. Besides 15 alkylthiazoles, -thiazolines and -thiazolidines, compounds with 2 and 3 S-atoms can also be identified: ethane-1,2-dithiole, diethyldisulfide, diethyltrisulfide, 2-methyl-1,3-dithiolane, 1,2-dithiane, thialdine, 1,2,4-trithiolanes, 1,2,4-trithianes and 2-methyl-thiazolidino-(3,4-b-)-thiazolidine. N,N'-dibutyrylcystamine shows an antioxidant effect.
