3-Deoxyanthocyanidin

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)[1], in Sorghum bicolor[1][2] and in purple corn (Nakatani et al., 1979)[1] (maíz morado).

3-Deoxyanthocyanidins are reported to be stable to color loss due to change in pH[3]. Synthetic 3-deoxyanthocyanidins with a carboxylate group at carbon 4 show unusually stable colorant properties at pH 7[1].

In Sorghum, the SbF3'H2 gene, encoding a flavonoid 3'-hydroxylase, seems to be expressed in pathogen-specific 3-deoxyanthocyanidin phytoalexins synthesis[4], for example in Sorghum-Colletotrichum interactions[5].
