Proanthocyanidins

More information in Books or onNLM PubMed
Definition: 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.      Other names Tannins, Condensed; Polymers, Anthocyanidin; Procyanidins; Condensed Tannins; Condensed Tannin; Tannin, Condensed; Anthocyanidin Polymers
