31P NMR of Phospholipid Membranes: Effects of Chemical Shift Anisotropy at High Magnetic Field Strengths
The 31P NMR spectrum of sonicated dipalmitoyl lecithin vesicles consists of two chemically shifted resonances, separated by -0.15 ppm, which arise from phosphate groups in phospholipid molecules on the insideand the outside of the spherical bilayer vesicles. The widths of the resonances are remarkably sensitive to the crystallineliquid crystalline phase transition, the magnetic field-strength, ...
متن کامل31P NMR of phospholipid glycerol phosphodiester residues.
Saponification of extracted tissue phospholipids yields a set of isolated glycerol 3-phosphoryl phospholipid polar headgroups from which semi-quantitative 31P NMR spectra can be obtained. The resonance signals from these molecules, which frequently have been reported as uncharacterized phosphate signals observed in perchloric acid extracts of tissue, can be used as an aid in the characterizatio...

this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
31P-NMR signals from inner and outer surfaces of phospholipid membranes.
We showed earlier [ 1,2] that PMR spectroscopy of phospholipid membranes in the presence of paramagnetic ions makes it possible to distinguish between signals coming from the inner and outer surfaces of a membrane, since the signal from the N+(CH,), protons of the outer surface lecithin molecules is considerably shifted in comparison with the signal from the inner surface protons. As there are ...
متن کاملthe effect of consciousness raising (c-r) on the reduction of translational errors: a case study
در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
