The role of glycerides in baking
Journal of the Science of Food and Agriculture, 1954AbstractPart I. The historical development of the use of glycerinated fats in baking is traced and some essential differences between American and British practice are discussed. Glycerinated fat comprises mixtures of mono‐, di‐ and tri‐esters; it is commonly but incorrectly called ‘glyceryl monostearate’ and the commercial material in this country ...

A METHOD FOR THE ESTIMATION OF GLYCERIDES IN BLOOD
Canadian Journal of Biochemistry and Physiology, 1954A method has been devised by which neutral glycerides may be determined in 0.1 ml. of whole blood. Lipid is extracted from the blood with alcohol–ether, dissolved in chloroform, and saponified. The liberated glycerol is then oxidized with periodic acid and the resulting formaldehyde distilled into sodium sulphite solution.

The structure of the glycerides of ergot oils
Lipids, 1966AbstractThe oils from sclerotia or from suitable mycelial cultures ofClaviceps purpurea (ergot) contain up to 44% of ricinoleic acid but no free hydroxyl groups. This is due to the presence of, besides normal triglycerides, tetra‐acid, penta‐acid and hexa‐acid triglycerides.

ORD and CD studies of glycerides II. The effect of branching in saturated glycerides
Chemistry and Physics of Lipids, 1976Abstract The effect of branching in the acyl group on the ORD and CD curves of 1,2-isopropylidene-3-acyl-sn-glycerols, 3-acyl-sn-glycerols and tiacyl-sn-glycerols has been studied. Branching of the acyl group in 1,2-dimyristoyl-3-acyl-sn-glycerols reverses the sign of the rotation and CD effect compared to straight chain analogues.

Gas‐liquid chromatography of glycerides
Journal of the American Oil Chemists' Society, 1965AbstractAvailable techniques are reviewed for gas‐liquid chromatography of mono‐, di‐ and triglycerides and their chemical modification products. Major emphasis is placed upon optimum separation and quantitative estimation of the recorded peaks. Nonlinear rates of temp programming are shown to be superior to linear rates for maximum resolution of ...

Abstract The previous work on the heats of fusion of glycerides is reviewed. Additional data for many mixed acid saturated and unsaturated triglycerides is reported and a set of best heats of fusion values for the stable forms of tri-, di- and monoglycerides is given.

SummaryA theory has been presented for the formation of fats which gives the amounts of the various glyceride types equivalent to a random or modified restricted random distribution and at the same time gives a predominance of specific positional isomers.

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 ...

Molecular Arrangement in Glycerides
Fette, Seifen, Anstrichmittel, 1972AbstractThe main features of glyceride crystallization are discussed on the basis of earlier known crystal structures of glycerides and the new results, particularly on their structure in the liquid state. An analysis of the methyl end group packing is presented, which enables to predict whether a particular crystal form of a mixed triglyceride exists.

2.1. IntroductionThis chapter will touch on points ofgeneral consideration for preparing labeled fattyacids and on selected methods used to label fatty acids. Representative syntheses ofsome labeled fatty acids will be described, and typical analytical methods fordetermining isotope purities and label position will be covered.General reviews on ...
