Proanthocyanidins (also known as Anthocyanidin Polymers, Polymers, Anthocyanidin): Dimers and oligomers of flavan-3-ol units (CATECHIN analogs) linked mainly through C4 to C8 bonds to leucoanthocyanidins. They are structurally similar to ANTHOCYANINS but are the result of a different fork in biosynthetic pathways.
