Karlin, Kenneth D.; Gultneh, Yilma – Journal of Chemical Education, 1985
Discusses studies done in modeling the copper centers in the proteins hemocyanin (a dioxygen carrier), tyrosinase, and dopamine beta-hydroxylase. Copper proteins, model approach in copper bioinorganic chemistry, characterization of reversible oxygen carriers and dioxygen-metal complexes, a copper mono-oxygenase model reaction, and other topics are…

Valentine, Joan Selverstone; de Freitas, Duarte Mota – Journal of Chemical Education, 1985
Discusses superoxide dismutase (SOD) research and the properties of copper, zinc (Cu, Zn)-SOD. Emphasizes the controversy concerning the role of Cu,Zn-SOD and other SOD enzymes as protective agents in reactions involving dioxygen metabolism, and the properties of Cu, Zn-SOD that make it an interesting biological ligand for physical studies of…

Snyder, Solomon H. – Scientific American, 1985
Chemical messengers mediate long-range hormonal communication and short-range neural communication between cells. Background information on peptides, steroids, neuropeptides, and specialized enzymes is given. Investigations reveal that the two systems have many common intercellular messenger molecules. (DH)

Gehring, Walter J. – Scientific American, 1985
Basic architecture of embryo development appears to be under homeobox control (a short stretch of DNA). Outlines research on this genetic segment in fruit flies which led to identification of this control on the embryo's spatial organization. Indicates that molecular mechanisms underlying development may be much more universal than previously…

Pankuch, Brian – Computers in Chemical Education Newsletter, 1985
Describes the use of two interactive computer programs in a college chemistry course. The first is a commercially-available simulation program (for Apple microcomputers with game paddles) which demonstrates gas laws. The second is a teacher-developed molecular bonding simulation program. (JN)

Fuchs, Richard – Journal of Chemical Education, 1984
Isodesmic reactions are hypothetical chemical changes in which the number of bonds of a given type are retained but change in relation to one another. Discusses use of these reactions and reaction energy to measure deviations from additivity of bond energy. Also considers relationship of enthalpies to strain and resonance stability. (JM)

DeYoung, H. Garrett – High Technology, 1984
Discusses structure and function of enzymes, design of new enzymes and enzyme substitutes, and enzyme uses in industry, medicine, and wastewater treatment. The latter is a low-cost method which can remove as much as 99 percent of toxic substances found in many industrial wastewater streams. (JN)

Block, Eric – Scientific American, 1985
Discusses structures and characteristics of sulfur compounds which cause the odor of garlic and the crying which may result from an onion. These compounds are dependent on conditions of extraction and account for medical properties long ascribed to garlic and onions. (DH)

George, Philip; And Others – Journal of Chemical Education, 1984
Discusses the nature of experimental resonance energy, explaining how its magnitude depends upon choice of reference molecules from which bond energies are derived. Also explains how it can be evaluated more simply, without recourse to bond energies, as enthalpy change for a reaction predetermined by choice of reference molecules. (JN)

Boyd, Donald B. – Journal of Chemical Education, 1976
Presents designs for atomic models for building small cyclic molecules and demonstrates their use in the construction of beta-lactam antibiotic structures. (MLH)

Hayman, H. J. G. – Journal of Chemical Education, 1977
Describes the use of a Hewlett-Packard 9810A programmable desk calculator with plotter for drawing ball-and-line stereopairs as well as three-dimensional structural formulas which are useful for teaching stereochemical principles and molecular structure. (MLH)

Nakhleh, Mary B. – 2002
One of the more interesting areas of problem solving in chemistry attempts to answer the question, "What do students understand about the molecular level of chemistry?" This question is also implicit in the more traditional area of mathematical problem solving but in this paper, more focus is placed on devising ways to help students develop a…

Wunderlich, Bernhard – Journal of Chemical Education, 1973
Discusses the inclusion of knowledge on macromolecules into a freshman chemistry course which emphasizes topics in organic chemistry, polymer science and biochemistry, atoms, chemical thermodynamics, and inorganic chemistry. Indicates that the program is the only way to keep chemistry education up to date. (CC)

Salamone, J. C.; And Others – Journal of Chemical Education, 1973
Summarizes course offerings and degree programs conducted by organizational units in the area of polymer science and engineering. Indicates that current trends are characterized by creation of interdisciplinary polymer programs and increase of academic training at both graduate and undergraduate levels. (CC)
