The Chemistry of Coffee William F. Coleman
The paper Our Everyday Cup of Coffee: The Chemistry behind Its Magic by Marino Petracco provides a hearty blend of molecules for this month. The author deals with coffee at a number of different levels ranging from the economic and social to the still perplexing questions of flavor and aroma. The associated molecules demonstrate a range of structural features that students will benefit from examining in three dimensions.

Molecular Model of Tubocurarine William F. Coleman
Curare, the Karib name for the plant from which this molecule is derived, is used in traditional South American medicine and hunting because it is a muscle relaxant. The three papers by Brunsvold and Ostercamp (1, 2, 3) provide us with an abundance of candidates for Featured Molecules this month. All of the major compounds highlighted in the papers, and many of the intermediates in the synthetic schemes, have been added to our collection. Students should note the structural similarities of the various barbiturate species and of the steroid-based compounds, as well as the interesting proto-cage structure of curare. Careful examination of the conformation of the alkyl groups in various of the molecules, when looked at as Newman projections, should convince students that their expectations about staggering substituents on adjacent tetrahedral-like carbon atoms are met in the computations. However, they should also be aware that recent work casts some doubt on the traditional explanation for that staggering (1). Charged species are presented in the collection in ionic form, without counterions (those are given in the papers), and all species except curare and atricurium besylate (molecule 40 in the third paper) were optimized at either HF/631-G(d) or B3LYP/631-G(d). The latter two molecules were optimized using HF/STO-3.

Molecular Models of Plant Hormones William F. Coleman
The paper "Synthesis of Plant Auxin Derivatives and Their Effects on Ceratopteris richardii" by Corey E. Stilts and Roxanne Fisher describing an experiment begun in the organic labs and completed in a biochemistry cell biology lab provides the featured molecules for this month. The molecules in Figure 1 of that paper have been added to the collection. There is nothing particularly surprising about their structures, but students might be interested in seeing whether they can determine any structure/regulating effect relationships as the number of synthesized auxin derivatives grows. Additionally, students with little or no biochemistry background might wish to explore other systems that act as growth regulating hormones in plants, as an introduction to the variety of molecular structures that can display such bioactivity. Such molecules range from the very simple, ethene, to the adenine-derived cytokinins (an example of which, zealtin, is shown here) and the brassinosteroids. Brassinolide, a commonly occurring brassin, is also shown. These latter two structures have also been added to the molecule collection. All of the structures have been optimized at the HF/6-31G(d) level.

The Reaction Rolodex; A Web-Based System for Learning Reactions in Organic Chemistry Eric Mahan
This Web-based system of note cards has been developed to aid students in learning the vast number of reactions encountered in organic chemistry. A thorough knowledge of these reactions is essential for success in first- and second-semester organic chemistry courses. The reactions are organized by functional group and can be chosen from a menu at the left side of the Web page. Once a particular reaction has been selected, the main frame displays the reactant(s) and reagent(s) along with a question mark in place of the product. After considering the reaction as long as needed, the user can click the question mark to reveal the reaction product. Clicking the product will again hide the answer and regenerate the question mark so that the reaction can be practiced again. Selecting other reactions from the menu on the left allows them to be practiced in the same manner.
