Quercetin 3-sulfate
IUPAC 名称
[2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-4-oxo-4H-chromen-3-yl]oxidanesulfonic acid
描述
N-acyl-d-mannosamine, also known as quercetin 3-(hydrogen sulfate) or quercetin 3-monosulphate, is a member of the class of compounds known as 3-sulfated flavonoids. 3-sulfated flavonoids are flavonoids that are sulfated at the 3-ring position of the flavonoid skeleton. Thus, N-acyl-d-mannosamine is considered to be a flavonoid lipid molecule. N-acyl-d-mannosamine is practically insoluble (in water) and an extremely strong acidic compound (based on its pKa). N-acyl-d-mannosamine can be found in dill, which makes N-acyl-d-mannosamine a potential biomarker for the consumption of this food product. N-acyl-d-mannosamine may be a unique E.coli metabolite.
