Preferentially CC hydrolyzes ergosteryl and zymosteryl esters (PubMed:19111628). Required CC for mobilization of SEs from lipid particles/droplets, thereby playing CC a central role in lipid metabolism and sterol homeostasis. Sterol CC intermediates stored in SE and set free by SE hydrolases are recycled CC to the sterol biosynthetic pathway and converted to the final product, CC ergosterol, in the endoplasmic reticulum. Has also weak lipase activity CC toward triglycerides at neutral pH, however, the physiological CC relevance of this activity is unclear (PubMed:15922657, CC PubMed:19111628, PubMed:28866104). {ECO:0000269|PubMed:10515935, CC ECO:0000269|PubMed:14640980, ECO:0000269|PubMed:15713625, CC ECO:0000269|PubMed:15922657, ECO:0000269|PubMed:19111628, CC ECO:0000269|PubMed:28866104}.
