Metabolite Identification

Common Name

Cajanin

Description

Cajanin 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. Cajanin has been detected, but not quantified in, several different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, pigeon peas (Cajanus cajan), pulses, and robusta coffees (Coffea canephora). This could make cajanin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Cajanin.

Enzyme Details

1. UDP-glucuronosyltransferase 1-1

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.
Gene Name:: UGT1A1
Uniprot ID:: P22309
Molecular weight:: 59590.91
