The 3-Deoxyanthocyanidins and their glycosides (3-deoxyanthocyanins or 3-DA) are molecules with an anthocyanidins backbone lacking an hydroxyl group on carbon 3.
3-Deoxyanthocyanidins are yellow anthocyanidins that can be found primarily in ferns and mosses (Timberlake and Bridle, 1975, 1980), in Sorghum bicolor and in purple corn (Nakatani et al., 1979) (maíz morado).
3-Deoxyanthocyanidins are reported to be stable to color loss due to change in pH. Synthetic 3-deoxyanthocyanidins with a carboxylate group at carbon 4 show unusually stable colorant properties at pH 7.
In Sorghum, the SbF3'H2 gene, encoding a flavonoid 3'-hydroxylase, seems to be expressed in pathogen-specific 3-deoxyanthocyanidin phytoalexins synthesis, for example in Sorghum-Colletotrichum interactions.
