Sclerotherapy with ethanolamine oleate is an acceptable approach for treating esophageal varices, peptic ulcer disease, and Dieulafoy s lesions. Most of the re− ported complications associated with ethanolamine oleate have been anecdotal and include portal/mesenteric vein thrombosis [1], hepatotoxicity [2], acute renal failure [3], purulent meningitis [4], noncardiogenic pulmonary edema [5], sp...

The acyl group of acyl dihydroxyacetone phosphate was shown to be enzymatically transferred in guinea pig liver mitochondria to various acceptors such as lysolecithin, lysophosphatidyl ethanolamine and sn-glycerol3-phosphate to form lecithin, phosphatidyl ethanolamine and phosphatidate, respectively. Coenzyme A and Mg*, but not ATP, were required for this reaction. A rapid exchange of acyl grou...

In a continuation of the search for intermediates involved in the condensation of the a-carbon atoms of 2 glycine molecules (l), investigations were carried out with ethanolamine-l-C13,2-C14 (C13H20H-C14H2NH2). It was considered possible that the serine synthesized from administered glycine2-Cl4 is, at first, labeled only in the a-carbon atom, the P-carbon atom being derived from unlabeled, end...

Choline-containing pneumococcal cell wals are sensitive to autolysin, whereas ethanolamine-containing walls are not. Bacteria were labeled with radioactive peptidoglycan precursors while growing either in choline- or in ethanolaminecontaining media. Subsequently, the labeled cells were allowed to grow for four to five generations in nonradioactive medium supplemented with the alternative amino ...

Amine compounds are believed to have acceptable results regarding their use as clay swelling inhibitor and corrosion inhibitor additives in drilling fluids. It is crucial to know the capability of amine compounds to enhance the thermal stability of drilling fluid; herein, a water-based fluid composed of biopolymer and other additives as the proper representatives of muds used in the pay zone se...

A suspension culture of the moss Marchantia polymorpha was incubated with either [3H]ethanolamine or [3H]myristic acid, precursors of a glycosylphosphatidylinositol (GPI) anchor. By both of these a secretory protein of 47 kDa was consistently labelled. Amino acid composition analysis of the chromatographically purified 47-kDa protein exhibited the occurrence of ethanolamine and glucosamine at a...

The isolation of deoxycytidine diphosphate choline (1) and deoxycytidine diphosphate ethanolamine (2,3) from diverse biological sources suggests that these compounds may have important metabolic functions. The corresponding ribonucleotides, CDP-choline and CDP-ethanolamine, have been shown to be essential intermediates in the biosynthesis of phospholipides (4). In the present paper, the synthes...
