"As Simple as Possible, but Not Simpler"—The Case of Dehydroascorbic Acid  Robert C. Kerber
Textbooks routinely assign dehydroascorbic acid a tricarbonyl structure that is highly improbable in aqueous solution and inconsistent with its colorless appearance. Studies of oxidized forms of ascorbic acid are summarized here, and a plea is entered for accurate descriptions of chemical structures in this and other cases, even at the cost of some simplicity.

Radical Quenching of 1,1-Diphenyl-2-picrylhydrazyl: A Spectrometric Determination of Antioxidant Behavior  John M. Berger, Roshniben J. Rana, Hira Javeed, Iqra Javeed, and Sandi L. Schulien
Describes a colorimetric assay using the persistent radical 1,1-diphenyl-2-picrylhydrazyl to measure the activity of common antioxidants. This exercise is particularly appropriate for a course geared for nutrition or food science majors.

The Stereochemistry of Biochemical Molecules: A Subject to Revisit  Josep J. Centelles and Santiago Imperial
This article reports on errors in stereochemistry of complex hydrosoluble vitamin B12 molecule. Twenty-five popular biochemistry textbooks were examined for their treatment of the stereoisomery of vitamin B12. Mistakes, discrepancies, and oddities reported in vitamin B12 are just an example of this problem. Biochemistry textbook authors and teachers should pay more attention to the stereoisomery of biochemical molecules to avoid students confusion.
