Common Name4-Methoxyglucobrassicin
Description4-methoxyglucobrassicin is a member of the class of compounds known as alkylglucosinolates. Alkylglucosinolates are organic compounds containing a glucosinolate moiety that carries an alkyl chain. 4-methoxyglucobrassicin is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). 4-methoxyglucobrassicin can be found in a number of food items such as broccoli, chinese mustard, chinese cabbage, and capers, which makes 4-methoxyglucobrassicin a potential biomarker for the consumption of these food products.
