Proanthocyanidin - Wikipedia
Proanthocyanidins is a polymer that mainly contains monomers such as catechins and epicatechins, and usually has a C-C covalent bond between adjacent monomers called the B-type, or from an additional ether bond between adjacent monomers called A-type; the common connection method of natural oligomeric proanthocyanidins (OPCs) is the B-type .

Proanthocyanidins (PACs) are a class of polyphenolic compounds that are attracting considerable interest in the nutraceutical field due to their potential health benefits. However, knowledge about the chemistry, biosynthesis, and distribution of PACs is limited.
Proanthocyanidin - an overview | ScienceDirect Topics
Proanthocyanidins are phytonutrients formed by oligomerization or polymerization of subunits catechin, epicatechin, and their gallic acid esters. Proanthocyanidins are a component of many plants and thus form an integral part of the human diet.
