In enzymology, an alkenylglycerophosphoethanolamine hydrolase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are 1-(1-alkenyl)-sn-glycero-3-phosphoethanolamine and H<sub>2</sub>O, whereas its two products are aldehyde and sn-glycero-3-phosphoethanolamine.
This enzyme belongs to the family of hydrolases, specifically those acting on ether bonds (ether hydrolases). The systematic name of this enzyme class is 1-(1-alkenyl)-sn-glycero-3-phosphoethanolamine aldehydohydrolase. This enzyme participates in ether lipid metabolism.
