''' Apiose''' is a branched-chain sugar found as residues in galacturonans-type pectins; that occurs in parsley and many other plants. Apiose is a component of cell wall polysaccharides.<ref>{{Cite journal | doi = 10.1093/glycob/cww012 | pmid = 26848180 | title = Apiose: One of nature's witty games | journal = Glycobiology | volume = 26 | issue = 5 | pages = 430–442 | year = 2016 | last1 = Pičmanová | first1 = Martina | last2 = Møller | first2 = Birger Lindberg}}</ref>
Apiose 1-reductase uses <small>D</small>-apiitol and NAD<sup>+</sup> to produce apiitol-apiose, NADH, and H<sup>+</sup>.
Flavone apiosyltransferase uses UDP-apiose and 5,7,4'-trihydroxyflavone 7-''O''-β-<small>D</small>-glucoside to produce UDP, 5,7,4'-trihydroxyflavone (apigenin), and 7-O-β-<small>D</small>-apiosyl-(1->2)-β-apiitol-glucoside.
