Fosfolipaza A1 (EC 3.1.1.32) je fosfolipazni enzim koji uklanja 1-acil.[1] Njegovo sistematskim ime je fosfatidilholin 1-acilhidrolaza.[2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju

fosfatidilholin + H2O 2-acilglicerofosfoholin + karboksilat

Ovaj enzim ima znatno širu specifičnost od enzima EC 3.1.1.4, fosfolipaze A2. Za njegov rad je neophodan jon Ca2+.

Fosfolipaza A1 je komponenta zmijskog otrova, ali se takođe učestvuje i u normalnom metabolizmu pri formiranju masnih kiselina iz fosfolipida. U melanocitnim ćelijama gen fosfolipaze A1 može da bude regulisan MITF-om[6].
