A procedure for the simultaneous preparation of S-sulfo-L-cysteine and L-alanine 3-sulfinic acid is described. The method is based on the quantitative reaction between sulfite and S-(2amino-2-carboxyethylsulfonyl~L-cysteine. The yield was 95% for S-sulfo-Lcysteine and 9 1% for L-alanine 3-sullinic
A new reaction of S-(2-amino-2-carboxyethylsulfonyl)-L-cysteine (ACESC) with thiosulfate is described. The reaction proceeded quantitatively in formic or acetic acid solutions, yielding equimolar amounts of L-alanine sulfodisulfane (2-amino-2-carboxyethyl sulfodisulfane) and L-alanine 3-sulfinic aci
