Diphosphopyridine nucleotide pyrophosphorylase in the nuclei isolated from poisoned and regenerating rat liver

Abstract

TANNINS 481 4. The properties of the flavan-4-ol in comparison with those of the flavan-3-ol suggest that the hydroxyl group in position 4 might be involved in the biochemical condensation of flavan-3:4-diols, and also in the redness developed in these com- pounds and in associated or related condensed tannins.
