-name: flavonoid glucuronidation
+name: obsolete flavonoid glucuronidation
 namespace: biological_process
-def: "The modification of a flavonoid by the conjugation of glucuronic acid. The resultant flavonoid glucuronosides are often much more water-soluble than the precursor." [GOC:BHF, PMID:20056724]
+def: "OBSOLETE. The modification of a flavonoid by the conjugation of glucuronic acid. The resultant flavonoid glucuronosides are often much more water-soluble than the precursor." [GOC:BHF, PMID:20056724]
+comment: The reason for obsoletion is that this term represents a molecular function.
