| EC Number | 3.1.1.3 |
| Enzyme Function | FUNCTION: Hydrolyzes triglycerides, with a preference for substrates with short-chain lengths (C4 to C8). Has the highest activity with tributyrin (C4), followed by tricaproin (C6) and tricaprylin (C8). Can also hydrolyze vinylacetate (C2) and triolein (C18), but with lower efficiency. Has no activity with tripalmitin (C16). {ECO:0000269|PubMed:16575565}. |
