Proanthocyanidins

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.

Also Known As:

Procyanidins; Condensed Tannin; Condensed Tannins; Polymers, Anthocyanidin; Tannins, Condensed; Anthocyanidin Polymers; Tannin, Condensed
