Doses of 1.5 μ mol cholesteryl oleate ingested by Aeshna cyanea larvae were partially hydrolysed in the intestinal lumen and the liberated oleic acid absorbed, while free cholesterol and unhydrolysed cholesteryl oleate were eliminated in the faeces. Ingestion of [4- 14C]cholesterol dissolved in oliv...
