2D TOCSY with WATERGATE solvent suppression ( MLEVGPPH19SW).1D proton with WATERGATE solvent suppression ( P3913GP).Check to make certain that all material dissolve, if not the case, spin in microfuge for 5 min.Make up 10 mM samples of your unknown in 650 μL 90% H 2O/10% D 2O.Run ( zg) 2D TOCSY with WATERGATE solvent suppression ( MLEVGPPH19SW).Run ( zg) 1D proton with WATERGATE solvent suppresion ( P3913GP).Determine the offset and 90° pulse width ( paropt on p1, look for 360° null).Sit through the presentation and demonstration on using Topspin to collect 1D and 2D spectra and iNMR for processing spectra.Perform LS/MS runs on your unknown dipeptides and predict its amino acid composition from its observed mass.Dilute 20 μL to 500 μL (1/25 dilution) with H 2O and plance in an HPLC vial for the LC/MS analysis.Dilute 10 μL to 1.0 mL (1/100) with H 2O for UV/Vis analysis.Dissolve 1 mg of unknown dipeptide in 1 mL H 2O.Each group will be given a vial contain 10 to 15 mg of and unknown dipeptide.Mass spec analysis of dipeptide unknowns.Sit through overview of mass spectrometry and NMR spectrometry, with emphasis on the contributions of John Fenn and Kurt Wüthrich.ChemDoodle is also able to simulate the NMR and Mass spectra of your amino acids and peptides.You can also use ChemDoodle to create a 3D model of your amino acids and petides.mol file into the text box that comes up when you click on the Load icon. If you save your structures as MDL Molfiles you can reload them into ChemDoodle by copying-and-pasting the contents of.This a a structure application that you can use to draw structures of your amino acids and peptides.An online manual for Sparky can be found at If you want your own copy of Sparky you can download it from. Spectra processed with iNMR can be saved in a format that can be read by Sparky. This is a free application that is used to make resonance ansignments using 2D-NMR spectra.You will need to Map to the deptdir drive to access your data (\\students\deptdir\chem\Instruments\NMR\chem453_F12) It is located on the PC's in P468 and elsewhere on campus. This application can be used to process your data. ![]() ![]() There are manuals and tutorials available at the inmr site ( ).Use iNMR to process spectra and create input files for Sparky.You will need to Map to the deptdir drive to access your data (\\cass1\deptdir\chem\Instruments\NMR\chem453_F11) This application can also be used to process your data.It is used to be available on nearly all of the Windows PC's on campus until the Windows 7 upgrade(?) occured. You can also use it to process your data. This is the application that you used to collect your spectra.John Fenn's 2002 Nobel Lecture (Please read this one.).The Biological Magnetic Resonance Data Bank.Kurt Wüthrich's 2002 Nobel Lecture (Please read this one.).Overview of the the 2002 Nobel Prizes in Chemistry.1H-NMR Proton Resonance Assignments for Amino Acids in Peptides.Clark, Jim "Chemguide: Understanding Chemistry, NMR Spectroscopy " 2005.Wüthrich, Kurt "NMR of Proteins and Nucleic Acids " Wiley-Interscience 1986.Friebolin, Horst "Basic One-and Two-Dimensional NMR Spectroscopy " Wiley-VHC 2005."Nuclear Magnetic Resonance Spectroscopy " Chapter 11: Contemporary Instrumental Analysis Prentice Hall Press 2000. ![]() ![]()
