Lipid analysis.

The analysis of lipids remains at the periphery of the biotechnology arena. Methods for analysis of lipids still center around the proven methods of thin layer chromatography, gas chromatography, gas chromatography-mass spectrometry and, more recently, high performance liquid chromatography. Advances have been made recently in understanding the biological role of lipid-conjugated molecules. Encapsulation of active substances in lipids is receiving more attention in order to achieve cellular penetration.
