The determination of glyceride structure
Journal of the American Oil Chemists' Society, 1963SummaryMethods for the determination of glyceride structure are discussed. These fall, with some overlapping, into two categories: methods applicable to fats generally and methods applicable to the natural fats but not to fats generally.

The effects of glyceride structure on absorption and metabolism.
Annual Review of Nutrition, 1991The subtle effects of the stereochemistry of acyl glycerols are apparent from the cited studies. It is not adequate to simply measure the fatty acid composition of dietary lipids or chylomicrons generated from them. To understand the importance of stereospecific acyl glycerols, simplification of the systems is necessary because of the incredible ...

Determination of the glyceride structure of fats
Journal of the American Oil Chemists' Society, 1961AbstractA method has been described for the quantitative determination of the following six glyceride types in fats: SSS, SSU, SUS, SUU, USU, and UUU. The method involved a quantitative oxidation of the unsaturated acids in the whole fat to the corresponding dicarboxylic acids. The oxidized fat was separated on a liquid‐liquid partition column into two

The glyceride structure of Sapium sebiferum seed oil.
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1969Abstract Sapium sebiferum seed oil is known to contain some tetraester triglycerides. The oil was separated by preparative thin-layer chromatography into normal triglycerides (76.9%) and estolide (23.1%) components which were each subjected to stereospecific analysis procedures.

AbstractFive fats containing less common fatty acids, nutmeg butter (myristic), rapeseed oil (erucic, eicosenoic), peanut oil (arachidic, behenic, lignoceric), tung oil (eleostearic), and coriander seed oil (petroselinic) were oxidized, and the oxidized esterified glycerides were analyzed by gas‐liquid chromatography (GLC).

The influence of glyceride structure on the rate of autoxidation
Journal of the American Oil Chemists' Society, 1967AbstractThe rate of autoxidation of mixtures of triunsaturated glycerides and tridecanoin was decreased by randomization with sodium methoxide. A theory, based on the hexagonal packing of glyceride acyl chains in the molten state, was proposed which accounted for the observed efforts on the rate of autoxidation.

Changes in the contents and compositions of lipid classes and water-soluble components were examined in maturing soybean seed. At the first stage of seed development, triglyceride formation was very slow, and considerably large quantity of free fatty acids, phosphatidic acid, monoglyceride, and diglyceride were accumulated.

The glyceride structure of natural fats. II. The rule of glyceride type distribution of natural fats
Journal of the American Oil Chemists' Society, 1953SummaryIt has been shown that the glyceride‐type composition of a natural fat can be calculated from the total mol per cent of saturated acids and the total mol per cent of trisaturated glycerides, in accord with a new rule of glyceride‐type distribution, which is stated as follows:The glyceride‐type composition of any natural fat is that obtained by ...

The glyceride structure of swine depot fat
Journal of the American Oil Chemists' Society, 1959Summary and ConclusionsA male pig was reared for three months on a diet containing about 1% fat and 0.2% dienoic acid. The back fat was fractionated into glyceride types by crystallization methods, and the fatty acid composition of each was determined by the spectrophotometric procedure.

SummaryExperimental evidence from the literature is given to support the hypothesis that the GS3 which may be present in natural fats cannot be in excess of the quantity which can exist in the fluid statein vivo. It is suggested that solid fat is not producedin vivo because the mode of action of lipolytic enzymes allows them to form only liquid fats.
