Ellagic acid acetyl-arabinoside
IUPAC 名称
(3S,4R,5R,6S)-4,5-dihydroxy-6-({7,13,14-trihydroxy-3,10-dioxo-2,9-dioxatetracyclo[6.6.2.0⁴,¹⁶.0¹¹,¹⁵]hexadeca-1(15),4(16),5,7,11,13-hexaen-6-yl}oxy)oxan-3-yl acetate
描述
Ellagic acid acetyl-arabinoside is a member of the class of compounds known as hydrolyzable tannins. Hydrolyzable tannins are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit. Ellagic acid acetyl-arabinoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Ellagic acid acetyl-arabinoside can be found in red raspberry, which makes ellagic acid acetyl-arabinoside a potential biomarker for the consumption of this food product.
