Structural identification of the beta-hydroxy fatty acid-based diester preen gland waxes of shorebirds

J Nat Prod. 2007 Nov;70(11):1804-7. doi: 10.1021/np070254z. Epub 2007 Oct 26.


The intact C33-C52 diester wax esters of the preen gland of the shorebirds Limosa lapponica, Pluvialis squatarola, and Pluvialis fulva were determined, using synthesized standards, to comprise predominantly C12-C16 beta-hydroxy fatty acids esterified with a C8-C18 fatty acid at the beta-hydroxy position and with predominantly C12-C20 fatty alcohols esterified at the carboxyl group.
