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. Centelles, Josep J.; Imperial, Santiago. J. Chem. Educ. 2005, 82, 75.

Orgo Cards: Organic Chemistry Review (Steven Q. Wang, Babak Razani, Edward J. K. Lee, Jennifer Wu, and William Berkowitz) Eugene Gooch The major strength of this product lies in coverage of the reaction mechanisms. Mechanisms are written out using curved arrow notation, steps are numbered, and a sentence describes the details of each step. Efforts are made to describe both ionic and radical mechanisms accurately. Stereochemical details are integrated into the descriptions of reactions and their mechanisms. Gooch, Eugene. J. Chem. Educ. 2003, 80, 1009.

SOS: A Mnemonic for the Stereochemistry of Glucose Ronald Starkey The mnemonic SOS (Same, Opposite, Same) can be helpful to recall the stereochemistry in either D-glucose or L-glucose. It refers to the configurations of C-2, C-3, and C-4 relative to that of C-5 in an aldohexose. Starkey, Ronald. J. Chem. Educ. 2000, 77, 734.

A New Method To Convert the Fischer Projection of Monosaccharide to the Haworth Projection Qing-zhi Zhang and Shen-song Zhang The D,L-configuration of a sugar in Haworth projection can be directly determined by designating the R,S-configuration of the highest-numbered asymmetric carbon; that is, the most distant carbon from the anomeric carbon. The R-configuration at this carbon corresponds to the D-family, and S- to the L-family. Zhang, Qing-zhi; Zhang, Shen-song. J. Chem. Educ. 1999, 76, 799.

Molecules, Crystals, and Chirality Il-Hwan Suh, Koon Ha Park, William P. Jensen, David E. Lewis* The development of the concept of chirality from the early work of Pasteur, van't Hoff and Le Bel to the work of Cahn, Ingold and Prelog is presented, and the constraints that chirality imposes on the symmetry of molecules - that chiral molecules may not possess an improper axis of rotation - is discussed.
