Formaldehid transketolaza (EC 2.2.1.3, dihidroksiacetonska sintaza) je enzim sa sistematskim imenom D-ksiluloza-5-fosfat:formaldehid glikolaldehidtransferaza.^[1]^[2]^[3] Ovaj enzim katalizuje sledeću hemijsku reakciju

D-ksiluloza 5-fosfat + formaldehid

\rightleftharpoons

gliceraldehid 3-fosfat + gliceron

Ovaj enzim je tiamin-difosfatni protein. On nije identical sa EC 2.2.1.1, transketolazom. Ovaj enzim takođe konvertuje hidroksipiruvat i formaldehid u gliceron i CO₂.
