Enzymes in the Biosynthesis of Hydrolyzable Tannins

1992
The two classes of hydrolyzable tannins (i.e., gallotannins and ellagitan-nins) have long been postulated to originate from 1,2,3,4,6-pentagalloyl-glucose as their common precursor. The biosynthesis of this pivotal ester was studied with enzymes from oak and sumac leaves. β-Glucogallin (l-O-galloyl-β-D-glucose), the first intermediate of this metabolic

Tannin structural elucidation and quantitative ³¹P NMR analysis. 2. Hydrolyzable tannins and proanthocyanidins.

Journal of agricultural and food chemistry, 2014
An unprecedented analytical method that allows simultaneous structural and quantitative characterization of all functional groups present in tannins is reported. In situ labeling of all labile H groups (aliphatic and phenolic hydroxyls and carboxylic acids) with a phosphorus-containing reagent (Cl-TMDP) followed by quantitative ³¹P NMR acquisition ...

Biosynthesis, Biodegradation, and Cellular Localization of Hydrolyzable Tannins

1999
Tannins occupy a prominent position among plant polyphenols, not only because of their widespread occurrence in the plant kingdom but also on grounds of their technological, ecological, and medical significance. Unfortunately, it is impossible to describe simply this large group of natural products on the basis of a common, general chemical structure ...
