6-Methoxymellein is a dihydroisocoumarin, a phenolic compound found in carrots and carrot purées. It is responsible for bitterness in carrots. [1] [2] It is a phytoalexin, induced in carrot slices by UV-C, [3] that allows resistance to Botrytis cinerea [4] and other microorganisms. [5]
6-Methoxymellein is formed from S-adenosyl methionine and 6-hydroxymellein by the enzyme 6-hydroxymellein O-methyltransferase with secondary production of S-adenosylhomocysteine. [6]
