Fig. 3.1. Argentation thin-layer chromatography plate of a L-P-P/P-L-P regioiso-meric mixture obtained by interesterification (left lane) total milk fat triacylglycerols (TAG middle lane) and CLA-P-P obtained from the reaction of 1,2-dipalmitin with CLA (right lane). P, palmitic acid L, linoleic acid. CLA-containing TAG were found between bands two and three and in band six. (Published with permission from Ref. 28 and redrawn from original.)... Fig. 3.1.

TLC is often used as a preparative technique to isolate individual lipid fractions for subsequent studies by a variety of analytical procedures. Preparative isolation of the sterol (Chitwood et al., 1985 Shetty et al., 1990) and triacylglyc-erol (Horutz et al., 1993) fractions have been reported. Preparative isolation of sterols may allow these lipids to be analyzed further by argentation TLC (Ditullio et al., 1965 Morris, 1966) or by GLC (Shetty et al., 1990). Moreover, preparative isolation of triacylglycerols will allow for TLC analysis of glyceryl ethers (Snyder, 1971) and HPLC analysis of specific triacylglycerols (Horutz et al., 1993). Experiment 7 is concerned with a preparative procedure for the analysis of sterols by argentation TLC. [Pg.288]

Unsaturated fatty acids or their triacylglycerols, as well as unsaturated aldehydes obtained through autoxidation of lipids (cf. 3.7.2.1.5), can be separated by argentation chromatography . The separation is based on the number, position and configuration of the double bonds present. The separation mechanism involves interaction of the r-electrons of the double bond with Ag" ions, forming a reversible TT-complex of variable stability ... [Pg.168]
