Malvidin 3-(6''-p-caffeyglucoside)
IUPAC 名称
3-{[(2S,3R,4S,5S,6R)-6-({[(2E)-3-(3,4-dihydroxyphenyl)prop-2-enoyl]oxy}methyl)-3,4,5-trihydroxyoxan-2-yl]oxy}-5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-1λ⁴-chromen-1-ylium
描述
Malvidin 3-(6''-p-caffeyglucoside) is a member of the class of compounds known as anthocyanidin 3-o-6-p-coumaroyl glycosides. Anthocyanidin 3-o-6-p-coumaroyl glycosides are anthocyanidin 3-O-glycosides where the carbohydrate moiety is esterified at the C6 position with a p-coumaric acid. P-coumaric acid is an organic derivative of cinnamic acid, that carries a hydroxyl group at the 4-position of the benzene ring. Malvidin 3-(6''-p-caffeyglucoside) is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Malvidin 3-(6''-p-caffeyglucoside) can be synthesized from cis-caffeic acid. Malvidin 3-(6''-p-caffeyglucoside) can also be synthesized into malvidin. Malvidin 3-(6''-p-caffeyglucoside) can be found in common grape, which makes malvidin 3-(6''-p-caffeyglucoside) a potential biomarker for the consumption of this food product. Malvidin 3-(6''-p-caffeyglucoside) may be a unique S.cerevisiae (yeast) metabolite.
