| EC Number | 3.1.1.3 |
| Enzyme Function | FUNCTION: Acid lipase that can hydrolyze a range of triacylglycerols but is not active on phospholipids (PubMed:15322116). In vitro, hydrolyzes triolein, trilinolein, triricinolein, tripalmitin, trilaurin and tricaprin (PubMed:15322116). May play a role in the regulation of lipolysis in germinating seeds (PubMed:15322116). {ECO:0000269|PubMed:15322116}. |
