Ioana Nicolau; Anca Paun; Codrut¸a C. Popescu; Niculina D. Ha?dade; Mihaela Matache – Journal of Chemical Education, 2023
This communication describes an updated experiment of peptide synthesis, involving determination of the loading capacity of a Fmoc-protected amino functionalized resin using UV-vis spectroscopy and a subsequent synthesis of a dipeptide in order to exemplify the experimental solid-phase synthesis procedure as an alternative technique in organic…

Matthew J. Satusky; Hunter Wilkins; Bryant Hutson; Mahfuz Nasiri; Dillon E. King; Dorothy A. Erie; Thomas C. Freeman Jr. – Journal of Chemical Education, 2022
Undergraduate research experience is critical to success in postgraduate research settings. The recent movement away from "cookbook" style laboratories to course-based undergraduate research experiences (CUREs) in undergraduate laboratories has allowed universities to provide inclusive research experience while bypassing the limitations…

Jeyarajaguru, Kabilan Shanmugampillai – Journal of Educators Online, 2023
The COVID-19 pandemic crisis has modified teaching and learning throughout the world. The developments in Information Communication Technology tools have played a critical role in the education community. During the pandemic, the organization and conduction of theory classes in Universities across India were managed reasonably on one side, but the…

Sedky, Nada K.; Arafa, Reem K. – Biochemistry and Molecular Biology Education, 2022
Nowadays, novel Biochemistry lab techniques are being introduced at a very fast pace in scientific research. This requires development of new labs for undergraduate Biochemistry courses to equip the students with up-to-date techniques. However, the time limit of Biochemistry labs for undergraduate students represents a major obstacle. This article…

Rodriguez, Jon-Marc G.; Towns, Marcy H. – Journal of Chemical Education, 2019
Analogies are useful tools instructors can use to help make challenging concepts less abstract by drawing connections to familiar contexts. In this paper we provide an overview of the various analogies published in the education literature that are situated in the context of enzyme kinetics, including narrative-based analogies (analogies intended…

Craig, Paul A. – Biochemistry and Molecular Biology Education, 2020
Lab courses are a significant component of biochemistry and molecular biology (BMB) education. In teaching the labs, we combine established techniques with novel approaches. Lab formats have also moved from traditional cookbook style labs to guided inquiry to course-based undergraduate research experiences (CUREs), where faculty bring their own…

Christopher T. Jurgenson – Journal of Chemical Education, 2022
Structures of 10 proteins from the Protein Data Bank were 3D printed as part of an undergraduate biochemistry teaching laboratory. All structures were successfully printed in either a space filling surface representation or a cartoon representation that traces the Ca carbon atoms of each amino acid residue. All structures were printed using…

Ma, Xiaoyu; Swedlund, Peter J. – Journal of Chemical Education, 2021
An experiment was developed for a first year food chemistry laboratory course that demonstrates the influence of several aspects of polysacharide structure on the rate of amylase catalyzed hydrolysis. The experiment would be particularly well-suited to a first year chemistry course that was targeted at nonchemistry majors, such as health related…

Perera, Viveka; Acharya, Baku; Patrick, Amanda L.; Mlsna, Deb – Journal of Chemical Education, 2020
Mass spectrometers are ever-increasingly powerful, user-friendly, and affordable. Thus, the addition of mass spectrometry experiments into the undergraduate laboratory curriculum is now both feasible and an effective tool to introduce students to relevant instrumentation. Here an experiment demonstrating the use of a high-resolution electrospray…

Mussi, María Alejandra; Actis, Luis A.; de Mendoza, Diego; Cybulski, Larisa E. – Biochemistry and Molecular Biology Education, 2014
A laboratory exercise was designed to illustrate how physical stimuli such as temperature and light are sensed and processed by bacteria to elaborate adaptive responses. In particular, we use the well-characterized Des pathway of "Bacillus subtilis" to show that temperature modulates gene expression, resulting ultimately in modification…

Girard, Dorothée; Rondeau, Philippe; Catan, Aurélie; Planesse, Cynthia; Giraud, Pierre; Bourdon, Emmanuel – Biochemistry and Molecular Biology Education, 2014
Due to the growing incidence of diabetes in developed nations, there is a compelling case to be made for teaching graduate students more deeply about mechanisms underlying this disease. Diabetes is associated with enhanced oxidative stress and protein glycation via the covalent binding of glucose molecules. Albumin represents the major plasmatic…

Bredeston, L. M.; Marciano, D.; Albanesi, D.; De Mendoza, D.; Delfino, J. M. – Biochemistry and Molecular Biology Education, 2011
This article describes a simple and robust laboratory exercise on the regulation of membrane unsaturated fatty acid composition in bacteria by a decrease in growth temperature. We take advantage of the well characterized Des pathway of "Bacillus subtilis", composed of a [delta]5-desaturase (encoded by the "des" gene) and the canonical…

Huisman, Andrew J.; Hartsell, Lydia R.; Krueger, Brent P.; Pikaart, Michael J. – Journal of Chemical Education, 2010
We developed a modular pair of experiments for use in the undergraduate physical chemistry and biochemistry laboratories. Both experiments examine the thermodynamics of the binding of a small molecule, eosin Y, to the protein lysozyme. The assay for binding is the quenching of lysozyme fluorescence by eosin through resonant energy transfer. In…

Chan, Yan Mei; Hom, Wendy; Montclare, Jin Kim – Journal of Chemical Education, 2011
Chemistry has become increasingly multidisciplinary. Starting in middle school and high school, however, the different disciplines are taught as distinct subjects and little effort is made to emphasize overlapping concepts. Development of innovative approaches to teaching science through the integration of technology is needed to provide students…

Carpenter, Nancy E.; Pappenfus, Ted M. – Journal of Chemical Education, 2009
An interdisciplinary, two-credit, one-semester laboratory course required of second-year chemistry and biochemistry majors at a small, rural, undergraduate liberal arts institution is described. During the first half of the course students are provided instruction in chemical information resources, scientific communication, advanced techniques,…
