Chemical Information

FooDB Name

Cajanin

Description

Cajanin, also known as cajinin, belongs to the class of organic compounds known as 7-o-methylisoflavones. These are isoflavones with methoxy groups attached to the C7 atom of the isoflavone backbone. Thus, cajanin is considered to be a flavonoid lipid molecule. Cajanin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Cajanin has been detected, but not quantified in, a few different foods, such as coffee and coffee products, pigeon pea, and pulses. This could make cajanin a potential biomarker for the consumption of these foods.
