Chemical Information
FooDB NameMethylajoene
DescriptionMethylajoene, also known as 1,2-butadien or 1-methylallene, is a member of the class of compounds known as acyclic allenes. Acyclic allenes are acyclic hydrocarbons (and by extension, derivatives formed by substitution) having two double bonds from one carbon atom to two others. Methylajoene can be found in soft-necked garlic, which makes methylajoene a potential biomarker for the consumption of this food product.
