Lipidomics of the chicken egg yolk: high-resolution mass spectrometric characterization of nutritional lipid families.

摘要: Abstract While previous studies have characterized the fatty acids and global lipid families of chicken egg yolk, there been no publications characterizing individual lipids in these families. Such an in-depth characterization yolk is essential to define potential benefits consumption for supply structural anti-inflammatory lipids. Historically, major focus has on cholesterol content eggs negative health this lipid, while ignoring roles membranes as a precursor other sterols. A detailed analysis lipids, using high-resolution mass spectrometric analyses tandem spectrometry characterize acid substituents complex was used generate first within Egg yolks were isolated from commercial (Full Circle Market) extracted with methyl-t-butylether before via spectrometry. This analytical platform demonstrates that provide rich nutritional source required homeostasis. These include dominant glycerophosphocholines (GPC) (34:2 36:2), plasmalogen GPC (34:1, 36:1), glycerophosphoethanolamines (GPE) 38:4 GPE (36:2 34:1), glycerophosphoserines 38:4), glycerophosphoinositols (38:4), glycerophosphoglycerols (36:2), N-acylphosphatidylethanolamines (NAPE) (56:6), NAPE (54:4 56:6), sphingomyelins (16:0), ceramides (22:0 24:0), cyclic phosphatidic (16:0 18:0), monoacylglycerols (18:1 18:2), diacylglycerols (36:3 triacylglycerols (52:3). Our data indicate energy-rich In addition, possess ω-3 ω-6 are precursors endogenous mediators. valuable addition diets individuals do not issues.
