Modification and Stabilization of Anthocyanins

Modification of anthocyanins is responsible for the stabilization of vacuolar anthocyanins. Cytosolic modification reactions include glycosylation, methylation, and acylation immediately following the synthesis of anthocyanidin aglycones. Knowledge of the biochemistry and molecular biology of these modification reactions, and the enzymes involved, has increased dramatically due to the molecular cloning of the genes encoding these enzymes from a variety of plant species in the last decade. Recent advances in the modification of anthocyanins are summarized and discussed in terms of fundamental biochemistry and application for the modification and stabilization of anthocyanins.KeywordsAcyl DonorAcyl AcceptorAcyl TransferAnthocyanin Biosynthetic PathwayAcyl SubstituentThese keywords were added by machine and not by the authors.
