  <name>S-Propenylcysteine</name>
  <description>S-propenylcysteine is a member of the class of compounds known as L-cysteine-s-conjugates. L-cysteine-s-conjugates are compounds containing L-cysteine where the thio-group is conjugated. S-propenylcysteine is soluble (in water) and a moderately acidic compound (based on its pKa). S-propenylcysteine can be found in soft-necked garlic, which makes S-propenylcysteine a potential biomarker for the consumption of this food product. </description>
