TLDR
In this paper, a procedure involving thin layer chromatography on silica impregnated with silver nitrate is described, which makes possible the separation of synthetic and natural glyceride mixtures into classes according to their degree of unsaturation, and within those classes the resolution of certain isomeric unsaturated glycerides.Abstract:
The paper describes a procedure involving thin layer chromatography on silica impregnated with silver nitrate, which makes possible the separation of synthetic and natural glyceride mixtures into classes according to their degree of unsaturation, and within those classes the resolution of certain isomeric unsaturated glycerides. The separations depend upon the ability of compounds having an olefinic double bond to form co-ordination complexes with the silver ion.read more

Separations of lipids by silver ion chromatography.
TL;DR: The possibility of separating lipid materials on the basis of the number, type, and position of the unsaturated centers they contain, by virtue of the complexing of these unsaturated bonds with silver ions, provides a relatively recent but now very important addition to the range of separatory methods available to lipid chemists and biochemists.

Photodensitometry in the thin-layer chromatographic analysis of neutral lipids
TL;DR: A procedure for photodensitometric quantitation of thin-layer chromatograms is described which can give a complete analysis of a mixture of neutral lipids in a single chromatogram without the necessity for reference mixtures.

TL;DR: The specificity of lipase for the primary hydroxyl groups of glycerides is indicated by the recent report of Borgstrom (7), and it will be impossible to demonstrate any specificity which the enzyme may have for particular long chain fatty acids.
