| EC Number | 3.1.1.3 |
| Enzyme Function | FUNCTION: Plays an important role in fat metabolism. It preferentially splits the esters of long-chain fatty acids at positions 1 and 3, producing mainly 2-monoacylglycerol and free fatty acids, and shows considerably higher activity against insoluble emulsified substrates than against soluble ones. {ECO:0000250|UniProtKB:P16233}. |
