Abstract

Section thickness in two-dimensional Fourier transform (FT) imaging is dependent on gradient strength and the shape of the radio-frequency pulses used to excite the nuclei. By manipulation of these parameters, it is possible to obtain 2.5-mm-thick sections in contiguous, multisection imaging. Because this method is efficient in imaging with long repetition times (TR), it effectively complements three-dimensional FT thin-section imaging techniques, which require imaging with short TRs. Fifteen double-echo, contiguous images of 0.9 X 0.9 X 2.5-mm resolution were obtained in 17.1 minutes for a TR of 2 seconds.

Comparative study of photodissociation and surface-induced dissociation by laser desorption Fourier transform mass spectrometry.

Photodissociation (PD) and surface-induced dissociation (SID) are compared for structural analysis of several nonvolatile compounds analyzed by laser desorption Fourier transform mass spectrometry (LD/FTMS). SID and PD of a porphyrin and two metalloporphyrins were investigated using a variety of experimental conditions. Optimum structural information is obtained from PD when parent ions are irradiated for relatively long times (10-30 s) using 575-nm radiation and short times (0.5-1 s) using 308- or 388-nm radiation. Shorter irradiation times in the visible region resulted in less efficient production of structurally significant product ions, while longer times in the ultraviolet region produced more nonspecific fragment ions, apparently at the expense of more structurally significant fragment ions. SID conversion efficiencies for the porphyrins are estimated for collision energies from 25 to 360 eV, with maximum conversion efficiency found using 62- and 115-eV collision energies for the two porphyrins studied. Results from a concurrent study on the combined use of PD and SID for MS/MS/MS are discussed in the context of these results. The MS3 ion spectra generated by the two dissociation techniques differ more significantly than MS2 product ion spectra. These data suggest some general guidelines for MSn studies of nonvolatile compounds analyzed by LD/FTMS, employing PD and SID for ion activation.

The pairing of the separated A and B chains of insulin and its derivatives, FTIR studies.

From the amide I bands of their deconvolved FTIR spectra, the S-thiomethyl derivatives of the insulin A, B, despentapeptide(26-30) B and desoctapeptide(23-30) B chains all contain significant amounts of ordered secondary structure. The intact B chain is considerably more ordered than either the A or the truncated B chains. Comparison of the spectra of the separated and mixed intact chains of insulin suggests further folding upon mixing of the chains leading to significant increases in ordered secondary structures, presumably because of stabilization by interaction of the chains. The interactions of the A chain with the DPI B chain appear to be weaker as compared to that with the intact B chain. The above results suggest that only the intact A and B chains contain sufficient structural information to recognize each other and interact to form a native-like structure which make the correct formation of the disulfide linkages possible.

Conformation of wheat gluten proteins. Comparison between functional and solution states as determined by infrared spectroscopy.

The conformation of wheat gluten proteins in their functional hydrated solid state (doughy state) has been studied for the first time using attenuated total reflection infrared spectroscopy. The amide I band of functional gluten proteins reveals that, in addition to beta-turns and alpha-helices, these proteins contain a significant amount of intra- and intermolecular extended beta-sheet structures. It appears that the solubilization of gluten proteins results in a major decrease of the amount of beta-sheet structures accompanied by an increase of the content of the beta-turn and alpha-helical conformations. In addition, the alpha-helices appears to be more distorted in solution than in the functional state. Furthermore, spectra of omega- and gamma-gliadins, which are two types of prolamins of differing amino acid sequence and conformation, confirm the results obtained on the functional protein system. These results suggest that viscoelastic gluten proteins may interact through aligned beta-sheets corresponding to their repetitive domains.
