Monogalactosyl diglyceride and digalactosyl diglyceride from commercial rapessed “lecithin”

Journal of the American Oil Chemists' Society, 1972
AbstractBy silicic acid column separation small quantities of glycolipid‐rich fractions have been isolated from commercial Swedish rapeseed “lecithin.” Major components in these fractions are monogalactosyl diglyceride and digalactosyl diglyceride which have been identified by Rf on thin layer chromatography specific color reactions and IR spectrometry.

Monogalactosyl diglyceride: A new neurolipid

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1967
Abstract 1. 1. Monogalactosyl diglyceride was isolated from bovine spinal cord and shown to be identical with the same lipid from spinach, except for fatty acid analysis. 2. 2. In particular, unequivocal evidence is presented for the presence of the β-glycosidic bond and the D configuration of the glyceryl moiety. 3. 3.

Gas-liquid chromatographic analysis of diglycerides

Chemistry and Physics of Lipids, 1971
Abstract A gas-liquid chromatography method for the resolution of 1,2-diglycerides of a given carbon number from the 1,3-isomers of the same carbon number is presented. Resolution of saturated diglycerides from the unsaturated diglycerides is also achieved, although complete resolution of unsaturated diglycerides is not obtained.

Glycosyl diglycerides from Pseudomonas rubescens

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1968
Abstract Glycolipids containing d -glucose and d -glucuronic acid have been isolated from Pseudomonas rubescens. The lipids belonged to the class of i -O-monoglycosyl diglycerides. In both lipids the glycosidic linkage had the β-configuration. Component fatty acids, which were the same for both lipids, ranged from C13 to C19 and included saturated,

Synthesis and in Vitro Study of a Diglyceride Prodrug of a Peptide

Pharmaceutical Research, 1994
A diglyceride derivative of a pentapeptide renin inhibitor, the 1,3-dipalmitoyl-[Iva-Phe-Nle-Sta-Ala-Sta-acetyl]-glycerol was synthesized and tested in vitro as a potential prodrug for oral administration. The ability of the diglyceride analog to inhibit the renin activity was equivalent to that of the parent peptide after predigestion with pancreatic ...

Synthesis of monoglycosyl diglycerides and their derivatives

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1976
The Koenigs-Knorr condensation of 1,2- and 2,3-di-O-benzyl-sn-glycerols with acetobromohexapyranoses results in the formation of practically only 1,2-trans-glycosides. The latter have been used for the synthesis of a number of monoglycosyl diglycerides with diglyeride moieties with L and D configurations.

Lipase catalysed isomerisation of 1,2-(2,3)-diglyceride into 1,3-diglyceride. The crucial role of water

Biotechnology Letters, 1991
Enzyme catalyzed isomerisation of 1,2-dipalmitin into the 1,3-isomer is shown to occur with 1,3 regiospecific lipases. The mechanism of this transformation is elucidated and the crucial role of the water still present in the enzyme preparation is shown.

Diglyceride-transporting lipoproteins inLocusta

Journal of Comparative Physiology ? B, 1977
The majority of haemolymph proteins obtained from resting mature locusts are soluble in 50% saturated (NH4)2SO4 solution. Chromatographically, these proteins may be resolved on Sepharose 6B into three partially included fractions. The leading high molecular weight fraction, A, is predominant and all the diglyceride in “resting blood” is associated with

Mono‐ and diglycerides in industrial fats

Journal of the American Oil Chemists' Society, 1947
Summary The presence of mono‐ and diglycerides in raw and hydrolyzed fats and their effect on the yields of fatty acids obtained by distillation is discussed. Experiments carried out under conditions suitable for the esterification of mono‐ and diglycerides with fatty acids to form triglycerides indicate the presence of these mono‐ and diglycerides.

Release of arachidonate from diglyceride in human platelets requires the sequential action of a diglyceride lipase and a monoglyceride lipase

Biochemical and Biophysical Research Communications, 1981
Abstract Release of arachidonate from 2-arachidonyl diglyceride by human platelet microsomes was investigated. Diglycerides labeled with 14 C-stearate at sn-1 and with 3 H-arachidonate at sn-2 were used as a substrate for microsomal diglyceride lipase.
