Cover: Protein Chemistry
Students often have difficulties understanding that proteins routinely exist in both folded and unfolded states, and that protein unfolding is not equivalent to irreversible denaturation or aggregation. In Naked-Eye Detection of Reversible Protein Folding and Unfolding in Aqueous Solution, Tess M. Carlson, Kevin W. Lam, Carol W. Lam, Jimmy Z. He, James H. Maynard, and Silvia Cavagnero describe a novel, simple, and visually engaging illustration of the reversible interconversion between folded and unfolded protein states and of the dramatic effect of pH, temperature, and stabilizing/destabilizing cosolutes on protein conformation.
Protein chemistry is also explored in these articles:

Jonathan S. Rhoad suggests using a pair of writing assignments that challenge students to gain a deeper understanding of underlying concepts and to read their textbook critically in the Commentary Written Assignments in Organic Chemistry: Critical Reading and Creative Writing.
Making Connections in Chemical Education Research
Development of the Connected Chemistry as Formative Assessment Pedagogy for High School Chemistry Teaching ~ Mihwa Park, Xiufeng Liu, Noemi Waight
Unraveling the Complexities: An Investigation of the Factors That Induce Load in Chemistry Students Constructing Lewis Structures ~ Jessica M. Tiettmeyer, Amelia F. Coleman, Ryan S. Balok, Tyler W. Gampp, Patrick L. Duffy, Kristina M. Mazzarone, and Nathaniel P. Grove
Chemical Bonding
In Emphasizing the Significance of Electrostatic Interactions in Chemical Bonding, Bhawani Venkataraman describes a pedagogical approach to help students understand chemical bonding by emphasizing the importance of electrostatic interactions between atoms. A previously published article by Bhawani Venkataraman with Elinor Gottschalk, Visualizing Dispersion Interactions, uses an animation and accompanying activity to help students visualize how dispersion interactions arise.
Courses Built on Reactivity
In Reactivity III: An Advanced Course in Integrated Organic, Inorganic, and Biochemistry , Chris P. Schaller, Kate J. Graham, and Henry V. Jakubowski describe a new course that presents chemical reactions from the domains of organic, inorganic, and biochemistry that are not readily categorized by electrophile–nucleophile interactions. This is built on two previously published articles:
Reactivity I: A Foundation-Level Course for Both Majors and Nonmajors in Integrated Organic, Inorganic, and Biochemistry ~ Chris P. Schaller, Kate J. Graham, Brian J. Johnson, T. Nicholas Jones, and Edward J. McIntee
Reactivity II: A Second Foundation-Level Course in Integrated Organic, Inorganic, and Biochemistry ~ Chris P. Schaller, Kate J. Graham, Edward J. McIntee, T. Nicholas Jones, and Brian J. Johnson
Importance of Non-technical Skills
Anne E. Kondo and Justin D. Fair reveal in Insight into the Chemistry Skills Gap: The Duality between Expected and Desired Skills that companies value effective teamwork and communication skills. These non-technical skills can be achieved when a strong foundation of interprofessional skills has been taught and applied in scientific settings, such as through undergraduate research.
Periodic Table
Clarifying Atomic Weights: A 2016 Four-Figure Table of Standard and Conventional Atomic Weights ~ Tyler B. Coplen, Fabienne Meyers, and Norman E. Holden

Heterocyclic Compounds
Synthesis and Characterization of 2-Phenylimidazo[1,2-a]pyridine: A Privileged Structure for Medicinal Chemistry by Brandi S. Santaniello, Matthew J. Price, and James K. Murray, Jr. describes a straightforward hetrocyclic synthesis. The authors point out that heterocyclic compounds, in particular N-heterocycles, are pervasive in compounds of medicinal and biological interest, as revealed in:
A Graphical Journey of Innovative Organic Architectures That Have Improved Our Lives ~ Nicholas A. McGrath, Matthew Brichacek, and Jon T. Njardarson
An In-Pharm-ative Educational Poster Anthology Highlighting the Therapeutic Agents That Chronicle Our Medicinal History ~ Elizabeth A. Ilardi, Edon Vitaku, and Jon T. Njardarson
