Vicine is an alkaloid glycoside found mainly in fava beans, which are also called broad beans ("Vicia faba)". Vicine is toxic in individuals who have a hereditary loss of the enzyme glucose-6-phosphate dehydrogenase. It causes haemolytic anaemia, called favism. The formation of vicine in "Vicia faba" has been studied, but this natural formation has not yet been found.
