Abstract
There 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. Thus, substantial further study is required to clarify the pathways involved. An experimental program is proposed to achieve this objective.
