Biogenesis of Condensed Tannins — An Overview
1989There are currently four hypotheses as to how condensed tannins are produced in nature. In order to explain the 2,3-cis configuration of frequently encountered proanthocyanidin polymers, each of these biosynthetic proposals invoke isomerase enzymes or chemical intermediates not yet encountered in nature.

Interaction of Condensed Tannins with Biopolymers
1989Condensed tannins form complexes with a multitude of species, ranging in size from divalent and trivalent metal ions to macromolecules, both naturally occurring and synthetic. Many of these complexes are of low solubility, permitting detection by techniques as simple as precipitation. Determination of the interactions responsible for the initial events

An Overview of Condensed Tannin Structure
1989The proanthocyanidins are an important class of natural products forming the basis for various classes of flavonoid polymers such as the condensed tannins, phlobaphenes, and phenolic acids. Refining our understanding of the structure of polyflavonoids will lead to a better appreciation of their properties and help in developing their use as a renewable
