ABSTRACT
The egg contains lipids on a large scale, even in its outer region. The shell contains0.045%lipidsinthecuticulaand1.35%lipidsintheshellmembrane(Suyama etal.,1977).Neutralandpolarlipidsoccurinproportionsof5:1and6:1,respectively. Neutrallipidsconsistofmono-,di-,andtriacylglycerols(TAG),cholesterolandcholesterylesters,andfreefattyacids(FA).Themaincomponentsintheneutrallipid fraction of the shell and its adjoining layers are cholesterol and cholesteryl esters, in addition to diacylglyerols; the TAG content is low.
