A synthesis of racemic diether analogues of glyceryl phosphatides is reported which is applicable to unsaturated aliphatic substituents. The "oleyl" diether analogue of phosphatidyl ethanolamine has been synthesized.
The previous observation (BABIOR, B. M., J. Biol. Chem., 244, 449 (1969)) that the tritium isotope effect for the coenzyme B,,-dependent deamination of ethanolamine was smaller than the deuterium isotope effect prompted a reexamination of the various isotope effects observed in this reaction. Measurements of the rates of deamination of [l-D]and [l,l-Dn]ethanolamine showed that no secondary isot...
Cholinephosphotransferase catalyses the final step in the synthesis of phosphatidylcholine (PtdCho) via the Kennedy pathway by the transfer of phosphocholine from CDP-choline to diacylglycerol. Ethanolaminephosphotransferase catalyses an analogous reaction with CDP-ethanolamine as the phosphobase donor for the synthesis of phosphatidylethanolamine (PtdEtn). Together these two enzyme activities ...
Ethanolamine ammonia-lyase catalyzes the adenosylcobalamin (AdoCbl)-dependent conversion of ethanolamine to acetaldehyde and ammonia. It has been proposed that the mechanism of this and other AdoCbl-dependent rearrangements involves the formation and rearrangement of an organocobalamin in which a substrate fragment is coordinated to the corrin metal by a carbon-cobalt bond. In the case of ethan...
Trai poeti italiani contemporanei tradotti in persiano, compare Alda Merini. Merini e` molto celebre perche` le sue poesie conduce i lettori alla conoscenzadi un aspetto mondiale della lettteratura. Lo studio presente è dedicato a lei, perché Alda è una donna a cui la poesia ha fatto grande dono di sé e che ha dimostrato con le sue opere un grande impegno intellettuale nella condanna delle ist...
It will be noted from the large standard deviations of the top half of Table 1 that the material proved rather variable. There are some indications that 3,3-tetramethyleneglutarate has a greater effect on fructose pool size in dystrophic muscle, but this cannot be proved statistically on this sample. The lower half of Table 1 shows an effect of 3,3tetramethyleneglutarate on fructose labelling, ...
The bis-retinoid pigments that accumulate in retinal pigment epithelial cells as lipofuscin are associated with inherited and age-related retinal disease. In addition to A2E and related cis isomers, we previously showed that condensation of two molecules of all-trans-retinal leads to the formation of a protonated Schiff base conjugate, all-trans-retinal dimer-phosphatidylethanolamine. Here we r...
Objective(s): Endometritis is the inflammation of the uterine lining that is associated with infertility. It affects milk production and reproductive performance and leads to huge economic losses in dairy cows. Dimethyl itaconate (DI), a promising chemical agent, has recently been proved to have multiple health-promoting effects. However, the effects of DI on endometri...
