The major oxidation product of h2s is thiosulfate, which is then converted to sulfate and excreted in the urine
. (So, if h2s is the culprit, I should be low on sulfate in the urine
b/c I'm not metabolizing my own...I think that would be the case.)
-The primary location for the oxidation reaction is the liver (Deficient FMO3 enzyme in the liver = TMAU, similarity).
