Tyler A. Shaffer; Carlos U. Herrada; Avery M. Walker; Laura D. Casto-Boggess; Lisa A. Holland; Timothy R. Johnson; Megan E. Jones; Yousef S. Elshamy – Journal of Chemical Education, 2023
Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

Kong, Sunnie; Kumta, Shruti; Vardar-Ulu, Didem – Biochemistry and Molecular Biology Education, 2022
The COVID-19 pandemic emphasized the importance of peer communication networks for student outcomes. Herein, we describe the use of supplemental instructional videos created by former students and integrated into electronic lab notebooks, to restore the lost community-learning component using student voices in a de-densified upper-division…

do Nascimento, Agatha Santos; de Oliveira, Felipe Sales; Bianconi, M. Lucia – Biochemistry and Molecular Biology Education, 2019
The bibliometric analysis of the Brazilian periodical "Journal of Biochemistry Education" (JBE) covered the 117 articles published in 15 volumes in the period 2001-2017. Our results showed a positive trend in JBE publications with a significant increase in the number of articles since 2014, which can be related to the increase in…

Periyannan, Gopal R. – Biochemistry and Molecular Biology Education, 2019
Technique-centered biochemistry or molecular biology undergraduate laboratory curricula do not offer significant opportunities for thoughtful, in-depth exploration of the science to foster investigative learning. To demonstrate inclusion of inquiry-driven laboratory experiments into the undergraduate biochemistry and molecular biology curricula, a…

Protein Colorimetry Experiments That Incorporate Intentional Discrepancies and Historical Narratives
Astrof, Nathan S.; Horowitz, Gail – Journal of Chemical Education, 2018
A set of biochemistry experiments based on the technique of protein colorimetry is described. Students used the Biuret and Bradford assays to qualitatively and quantitatively assess solutions for protein. Two unique features of these experiments are (1) the use of intentional discrepancies within each experiment to promote critical thinking and…

Devor, Kenneth A. – Journal of Chemical Education, 1979
This inexpensive but informative experiment for undergraduate biochemistry students involves isolating phosphatidyl choline from spinach leaves. Emphasis is on introducing students to techniques of lipid extraction, separation of lipids, identification using thin layer chromatography, and identification of fatty acids. Three periods of three hours…
