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.

Werner and Jørgensen Bond Theory  David M. Whisnant, Laura Yindra
This simulation begins in the period around 1870 when chemistry is beginning to be organized. The concept, introduced by Kekulé and Couper, of tetravalent carbon atoms capable of linking to each other has permitted the rise of structural concepts in organic chemistry.

The Evolution of Bond Theory  David M. Whisnant, Laura Yindra
In chemistry lectures we have little time to discuss the history of chemistry. This simulation begins with the development of valence concepts in the 19th century. We will step back into the 19th century to see how theories of chemical combination changed during that time.

Elementary Bingo  Robert M. Hanson, Ira M. Hanson
Elementary Bingo is a simple Web page that creates Bingo cards for a classroom or social event activity associated with review and/or learning of the names and symbols of the elements. The essential element of the site is that every time the page is reloaded or printed, a unique set of Bingo cards is produced. As in ordinary Bingo, players receive Bingo cards that have chemical symbols. An announcer picks elements out of a hat (or beaker) and announces a chemical name. Players place markers on the symbol for that element if they have it on their card. Once a player has five across, five down, or five diagonally, they announce, "Bingo!" Their card is checked to see if, indeed, they do have the announced elements present.

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.

Enzyme Activity as a Function of pH  Paul Krause
A matched pair of documents providing an introduction to the role of pH in the regulation of enzyme activity. The tutorial document contains all the equations and graphs for students to use to study the role of pH in enzyme kinetics. In the EnzymeExercise twin document all quations are omitted so that students can develop these interactively. The Exercise document is also ideal for display during lecture where the ideas can be developed interactively with the class as a whole.

Biomolecules: this is a resource in the collection "Netorials". This set of modules will provide you with a descriptive overview of the four major classes of biomolecules found in all living organisms: carbohydrates, lipids, proteins, and nucleic acids. The Netorials cover selected topics in first-year chemistry including: Chemical Reactions, Stoichiometry, Thermodynamics, Intermolecular Forces, Acids & Bases, Biomolecules, and Electrochemistry.

Molecular Models of Products and Reactants from Suzuki and Heck Syntheses  William F. Coleman
Our Featured Molecules this month come from the paper by Evangelos Aktoudianakis, Elton Chan, Amanda R. Edward, Isabel Jarosz, Vicki Lee, Leo Mui, Sonya S. Thatipamala, and Andrew P. Dicks (1), in which they describe the synthesis of 4-phenylphenol using an aqueous-based Suzuki reaction. The authors describe the various ways in which this reaction addresses concerns of green chemistry, and point out that their product bears structural similarity to two non-steroidal anti-inflammatory drugs (NSAIDs), felbinac and diflunisal. A number of molecules from this paper and its online supplemental material have been added to the Featured Molecules collection. Students will first notice that the aromatic rings in the molecules based on a biphenyl backbone are non-planar, as is the case in biphenyl. If they look carefully at diflunisal, they will notice that the carbon atoms are in a different chemical environment. One way in which to see the effect of these differing environments is to examine the effect of atom charge on the energies of the carbon 1s orbitals. Figure 1 shows this effect using charges and energies from an HF/631-G(d) calculation. A reasonable question to ask students would be to assign each of the data points to the appropriate carbon atom. As an extension of this exercise students could produce similar plots using different computational schemes. Are the results the same; are they parallel. This would be a useful problem when dealing with the tricky question of exactly what is meant by atom charge in electronic structure calculations. Students with more expertise in organic chemistry could explore extending the synthesis of 4-phenylphenol to produce more complex bi- and polyphenyl-based drugs. This may well be the first time that they have seen coupling reactions such as the Suzuki and Heck reactions. Students in introductory and non-science-major courses might well find the NSAIDs to be an interesting group of molecules, and could be asked to find information on the variety of molecules that display the anti-inflammatory properties associated with NSAIDs. Do they find structural similarities? Are there various classes of NSAIDs? Are they familiar with any of these molecules? Have they taken any NSAIDs? If so, for what reason? Is there any controversy about any of the NSAIDs? As with all of the molecules in the Featured Molecules collections, those added this month provide us with a number of ways of showing students the practical relevance of what they sometime see only as lines on a page. Molecules do matter.
