| Enzyme Function | FUNCTION: Major lipase in white adipose tissue (By similarity). Involved in the metabolism of xenobiotics and of natural substrates. Hydrolyzes triacylglycerols and monoacylglycerols, with a preference for monoacylglycerols. The susceptibility of the substrate increases with decreasing acyl chain length of the fatty acid moiety. Catalyzes the synthesis of fatty acid ethyl esters (PubMed:1429692). Hydrolyzes retinyl esters (PubMed:12230550). {ECO:0000250|UniProtKB:Q8VCT4, ECO:0000269|PubMed:12230550, ECO:0000269|PubMed:1429692}. |
