Book Handbook of Phosphorus 31 Nuclear Magnetic Resonance Data 1990

Download or read book Handbook of Phosphorus 31 Nuclear Magnetic Resonance Data 1990 written by John C. Tebby and published by CRC Press. This book was released on 2017-11-22 with total page 1140 pages. Available in PDF, EPUB and Kindle. Book excerpt: To fully utilize Nuclear Magnetic Resonance (NMR) spectroscopy, a comprehensive and well-organized compilation of NMR data is necessary. While compilations have been available for other important NMR nuclei, such as carbon and fluorine, no comprehensive collection of data has been prepared for phosphorus-until now. The CRC Handbook of Phosphorus-31 Nuclear Magnetic Resonance Data provides a collection of 31P NMR chemical shifts for nearly 20,000 organic and inorganic phosphorus compounds. Each class of phosphorus compound is discussed. Bond types, stereochemistry (with the exception of metal complexes), media, important coupling constants, and data sources are included. The information is systematically organized according to coordination state, the atoms bound to phosphorus, and their connectivities. A comprehensive series of bar charts is also included to allow structure types to be assigned to chemical shift data. This handbook is an invaluable resource for all scientists working with phosphorus compounds, including chemists, biochemists, medical researchers, and pharmaceutical chemists.

Book Phosphorus 31 and Deuterium Solid state Nuclear Magnetic Resonance Studies of the Headgroup Conformation of Phosphonolipids in Biological and Model Membranes

Download or read book Phosphorus 31 and Deuterium Solid state Nuclear Magnetic Resonance Studies of the Headgroup Conformation of Phosphonolipids in Biological and Model Membranes written by Marie-Rose Van Calsteren and published by . This book was released on 1991 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid-state nuclear magnetic resonance (NMR) techniques were applied to the study of the phase behavior and to the determination of the headgroup conformation of phosphonolipids, both natural and synthetic. The results are compared with those for analogous phospholipids in biological and model membranes. $\sp{31}$P NMR was used to characterize the phase behavior of phospho- and phosphonolipids present in polar and total lipid extracts of the protozoa Tetrahymena thermophila. The $\sp{31}$P NMR spectra of aqueous dispersions of polar and total lipids consist in the partial superposition of two powder patterns, one for each phosphorus-containing lipid class. At low temperature, both lipid extracts give rise to lineshapes characteristic of the lamellar structure. Spectra of the polar lipids show that between 15 and 40$\sp\circ$C, a broad, reversible transition from bilayer to hexagonal phase takes place. On the other hand, the phase behavior for total lipids is different: no hexagonal phase is formed, the lipids remain in the bilayer phase at a higher temperature, and a transition to an isotropic phase occurs between 35 and 40$\sp\circ$C, which is not easily reversible. A large proportion of ethanolamine-containing lipids, both phosphate and phosphonate analogs, is responsible for the hexagonal phase formation observed with the polar lipids. When neutral lipids are present with the polar lipids, the bilayer is stabilized up to a higher temperature. One of the neutral lipid components, tetrahymanol, a pentacyclic triterpenoid, is believed to be responsible for this stabilization. The results show that the conformation of the headgroup up to the phosphorus atom is very similar in phospho- and phosphonolipids, i.e. the C2-C3-O-P torsion angle is nearly trans and the C3-O-P-C1 angle variable over the range of values investigated, with a bend at the phosphorus atom. Contrary to the phosphodiester moiety in analogous phospholipids which adopts a gauche-gauche conformation, two solutions for the next torsion angle O-P-C1-C2 were found around 100 and 130$\sp\circ$. The last segment P-C1-C2-N is nearly trans, whereas the corresponding O-C1-C2-N segment in phospholipids is gauche. Despite the differences in the torsion angle values, the overall appearance of the headgroup is similar for both phospho- and phosphonolipids. The headgroup first extends out of the bilayer plane, bending at the phosphorus atom and the terminal portion lies nearly parallel to the membrane surface. (Abstract shortened by UMI.).
