C24H25O13 (521.1295)

Petunidin 3-o-(6-acetyl-galactoside) is a member of the class of compounds known as anthocyanidin-3-o-glycosides. Anthocyanidin-3-o-glycosides are phenolic compounds containing one anthocyanidin moiety which is O-glycosidically linked to a carbohydrate moiety at the C3-position. Petunidin 3-o-(6-acetyl-galactoside) is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Petunidin 3-o-(6-acetyl-galactoside) can be found in highbush blueberry and lowbush blueberry, which makes petunidin 3-o-(6-acetyl-galactoside) a potential biomarker for the consumption of these food products.

3-{[(2S,3R,4S,5S,6R)-6-[(acetyloxy)methyl]-3,4,5-trihydroxyoxan-2-yl]oxy}-2-(3,4-dihydroxy-5-methoxyphenyl)-5,7-dihydroxy-1lambda4-chromen-1-ylium

C24H25O13 (521.1295)

Petunidin 3-o-(acetylglucoside) is a member of the class of compounds known as anthocyanidin-3-o-glycosides. Anthocyanidin-3-o-glycosides are phenolic compounds containing one anthocyanidin moiety which is O-glycosidically linked to a carbohydrate moiety at the C3-position. Petunidin 3-o-(acetylglucoside) is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Petunidin 3-o-(acetylglucoside) can be found in a number of food items such as summer grape, common grape, rubus (blackberry, raspberry), and grape wine, which makes petunidin 3-o-(acetylglucoside) a potential biomarker for the consumption of these food products. Petunidin 3-o-(acetylglucoside) may be a unique S.cerevisiae (yeast) metabolite.
