Marquioni, Vinícius; Nunes, Francis Morais Franco; Novo-Mansur, Maria Teresa Marques – Journal of Chemical Education, 2021
Mass spectrometry is essential for large-scale protein identification in proteomics. By database searching of mass spectrometry data, it is possible to identify proteins without the need to interpret MS/MS spectra (de novo sequencing), which is time-consuming and not feasible as a systematic tool in proteomic analysis. Many authors have reported…

Keithley, Richard B.; Sullivan, Dylan T.; Dodd, John M., II; Iyer, Kavya V.; Sarisky, Catherine A.; Johann, Timothy W. – Journal of Chemical Education, 2021
Techniques and instrumentation that involve fluorescence are used in many careers related to biology and biochemistry. However, due to the expense of instrumentation, the theory and practice of fluorescence spectroscopy is commonly concentrated in instrumental analysis in most curricula, a class rarely required for biology and biochemistry majors.…

Hadi D. Arman; Tu M. Ho; Kaitlyn Varela; Cynthia S. Veliz; Richard B. Zanni; Armando Rodriguez; Zhiwei Wang; Francis K. Yoshimoto – Journal of Chemical Education, 2023
Eleven different laboratory experiments were designed and executed throughout a semester to provide a meaningful research experience for 23 undergraduate biochemistry majors at UTSA. The topic of the semester was based on the idea of exploring new aspects to enhance our understanding of how the human body uses cytochrome P450 enzymes to metabolize…

Wagner, Eugene P.; Gronborg, Kai C.; Ghosh, Shreya; Saxena, Sunil – Journal of Chemical Education, 2019
Electron spin resonance (ESR) or electron paramagnetic resonance (EPR) spectroscopy is an incisive technique for the characterization of paramagnetic centers in inorganic, bioinorganic, and organic molecules and materials. These measurements are enabled with the help of paramagnetic species, such as organic free radicals and ions, electronically…

Takor, Gaius; Morgan, Christopher E.; Chiu, Liang-Yuan; Kendrick, Nashea; Clark, Emily; Jaiswal, Rohan; Tolbert, Blanton S. – Journal of Chemical Education, 2020
Two-dimensional nuclear magnetic resonance (2D NMR) techniques are regularly used for the determination of RNA structures. In an effort to introduce advanced level students who are generally not acquainted with or exposed to these techniques, this work, which has been designed as a practicum, utilizes a combination of 2D NMR techniques to help…

Miles, Deon T.; Wells, William G. – Journal of Chemical Education, 2020
Hands-on learning in a laboratory is an integral part of the undergraduate experience for chemistry students. However, with the onset of the COVID-19 pandemic, an opportunity for this approach was not possible. The pandemic has been forcing instructors to explore the remote setting instead of the laboratory. There are several commercially…

Boyce, Mary C.; Lawler, Nathan G.; Tu, Yingqi; Reinke, Stacey N. – Journal of Chemical Education, 2019
Metabolomics is the data-driven science of small molecules. Untargeted metabolomics, using liquid chromatography-high resolution mass spectrometry (LC-HRMS), differs greatly from targeted metabolite assays, using nominal mass LC-MS instruments, as it generates thousands of metabolite features which are not quantified and are identified "post…
