Apiose is a branched-chain sugar found as residues in galacturonans-type pectins; that occurs in parsley and many other plants.

Apiose 1-reductase uses D-apiitol and NAD⁺ to produce D-apiose, NADH, and H⁺.

Flavone apiosyltransferase uses UDP-apiose and 5,7,4'-trihydroxyflavone 7-O-beta-D-glucoside to produce UDP, 5,7,4'-trihydroxyflavone (apigenin), and [[7-O-[beta-D-apiosyl-(1->2)-beta-D-glucoside]]].
