TLDR
In this paper, an analytical procedure for studies on the composition of hydrogenated oils containing C20 and C22 fatty acids is presented, which involves an initial separation of esters by preparative gas liquid chromatography into fractions of equal chain length.Abstract:
An analytical procedure is presented for studies on the composition of hydrogenated oils containing C20 and C22 fatty acids The method involves an initial separation of esters by preparative gas liquid chromatography into fractions of equal chain length Each fraction is subsequently studied in detail by gas liquid chromatography, argentation thin layer chromatography, IR spectroscopy, and microozonolysis Results are presented from a study of the isomers of major monoenoic acids in commercial samples of rapeseed and partially hydrogenated rapeseed oilsread more

Some Contemporary Applications of Open-Tubular Gas-Liquid Chromatography in Analyses of Methyl Esters of Longer-Chain Fatty Acids†
R. G. Ackman,C. A. Eaton +1 more
TL;DR: The use of wall-coated open-tubular (capillary) gas-liquid chromatographic columns has been shown to be particularly suitable for rapid screening of fats and oils for total docosenoic acid without interference from other components as discussed by the authors.
Journal ArticleDOI
High performance liquid chromatography and glass capillary gas chromatography of geometric and positional isomers of long chain monounsaturated fatty acids.
TL;DR: Most of the individual positional isomers of monounsaturated fatty acids of varying chain length could be separated and determined in the glass capillary GC step with the exception of those isomers containing the double bond in a relatively high ω-position.

The effects of partially hydrogenated marine oils on the mitochondrial function and membrane phospholipid fatty acids in rat heart
Rolf Blomstrand,Lennart Svensson +1 more
TL;DR: Dietarycis isomers of 22∶1 seem to have a specific ability to interfere with cardiac ATP synthesis and also to alter the fatty acid composition of cardiolipin of rat heart.

Industrial utilization of C21 dicarboxylic acid
TL;DR: The potential industrial applications for the dibasic acid and some of its derivatives in ink resins, adhesives, coatings, lubricants, plasticizers, corrosion inhibitors, synthetic coolants; emulsions; temporary coatings; floor polishes; and industrial, household, and institutional cleaners are discussed in this paper.

The chemical constitution of natural fats.
TL;DR: In this article, a brief summary of the composition of the natural fats which come within the scope of a discussion upon the subject of triglyceride fats in human nutrition is given, by considering, first, typical compositions of human and other,mammalian fats (depot, liver and milk) and, subsequently, the compositions of the vegetable and marine animal fats which are most commonly utilized as sources of human dietary fat.

Pathological effects of dietary rapeseed oil in rats.
A.M.M. Abdellatif,R.O. Vles +1 more
TL;DR: It was shown that the fatty infiltration of the heart and skeletal muscles occurs after 1 day of RSO feeding and becomes most severe after 3–6 days, and erucic acid appears to be the constituent in RSO responsible for its pathological effects.

TL;DR: Alkaline isomerization combined with ozonization-hydrogenation-GLC combined with these procedures was applied to determine the unusual double bond structures, and permits positional identification of an internal double bond.

Cardiac Lipid Changes in Rats Fed Oils Containing Long-Chain Fatty Acids
TL;DR: In this paper, the composition of the cardiac fatty acids and the histopathology in rats receiving oil as 40% of calories were studied after 3, 7, 14 and 28 days.
