1,2,3-Trinonadecanoyl glycerol, a triacylglycerol incorporating nonadecanoicacid at the sn-1, sn-2, and sn-3 positions, serves as an internal standard in the quantification of triacylglycerols in human serum via capillary gas chromatography.
1,3-Dinonadecanoyl glycerol, a diacylglycerol with nonadecanoicacid at the sn-1 and sn-3 positions, serves as a standard in quantifying diacylglycerols in synthetic milk fat. This is achieved through solid phase extraction (SPE) HPLC, employing an evaporative light scattering detector (ELSD).
