|
| Comment(s) |
|---|
- Involved in the pathway by which many flowering plants make
anthocyanin (glycosylated anthocyandin) flower pigments.
- The intermediates are transformed into cis- and trans-
dihydroquercetin, which the enzyme can also oxidize to quercetin.
- Acidification of the products gives anthocyanidin, which, however,
may not be a natural precursor of the anthocyanins.
