A-DNA and B-DNA: Comparing Their Historical X-ray Fiber Diffraction Images  Amand A. Lucas
This paper provides a comparative explanation of the structural content of the diffraction diagrams of A-DNA and B-DNA that facilitated the discovery of the double-helical structure of DNA by Watson and Crick in 1953. This analysis is supported a method that simulates both A-DNA and B-DNA X-ray images optically.

Kinetic Analysis of Amylase Using Quantitative Benedict's and Iodine Starch Reagents  Beverly Cochran, Deborah Lunday, and Frank Miskevich
This laboratory emphasizes that enzymes mediate the conversion of a substrate into a product and that either the concentration of product or reactant may be used to follow the course of a reaction. It does so by using an inexpensive scanner and open-source image analysis software to quantify amylase activity through the breakdown of starch and the appearance of glucose.

Structures for the ABO(H) Blood Group: Which Textbook Is Correct?  John M. Risley
Six textbooks and two Internet sites show different structures for the A, B, and O(H) antigens of the ABO(H) blood group, but none of them are correct. This article emphasizes the correct molecular structures because it is important to distinguish between those carbohydrates that make up the antigens and those that are not part of the antigenic structures.

Amino Acid Complementarity: A Biochemical Exemplar of Stoichiometry for General and Health Sciences Chemistry  Ed Vitz
Calculations demonstrating amino acid complementarity are presented as an interesting application of stoichiometry. Food proteins are said to have complementary amino acids when the proteins combine to provide amino acids in the proper stoichiometric ratios to synthesize human protein. Implications for vegetarian diet, efficiency of food production, and diet adaptations in various cultures are explored briefly.

A Supramolecular Approach to Medicinal Chemistry: Medicine Beyond the Molecule  David K. Smith
This article emphasizes a conceptual view of medicinal chemistry, which has important implications for the future, as the supramolecular approach to medicinal-chemistry products outlined here is rapidly allowing nanotechnology to converge with medicine. In particular, this article discusses recent developments including the rational design of drugs such as Relenza and Tamiflu, the mode of action of vancomycin, and the mechanism by which bacteria develop resistance, drug delivery using cyclodextrins, and the importance of supramolecular chemistry in understanding protein aggregation diseases such as Alzheimer's and CreutzfieldJacob.

A Modular Laser Apparatus for Polarimetry, Nephelometry, and Fluorimetry in General Chemistry  Scott A. Darveau, Jessica Mueller, April Vaverka, Cheri Barta, Anthony Fitch, Jessica Jurzenski, and Yvonne Gindt
We present an apparatus suitable for multiple uses in the general chemistry laboratory including polarimetry, fluorescence, and nephelometry. The open design of the instrument also decreases the chance that students will contract the "black-box syndrome" that seems to develop when using instruments that only provide the final data in an experiment without showing how the measurements are obtained.

A simple procedure for the crude purification of a chromoprotein suitable for a general chemistry laboratory. The protein, phycocyanin, is easy to purify and very stable. It contains a chromophore that can serve to report the integrity of the protein structure: the chromoprotein is dark blue when the protein is folded in its native conformation, and it turns a very pale blue when the protein is unfolded or denatured.
