Describes an undergraduate enzyme kinetics experiment which uses bovine erythrocyte carbonic anhydrase, a very stable enzyme commercially available in lyophilized form. Includes background information, reactions involved, procedures used, and the calculation of typical results obtained. (JN)

Discusses possible reasons for the variations in current biochemistry laboratories (including staff expertise, equipment limitations, no laboratory textbook with modern experiments, and diverse student backgrounds). Also proposes a more uniform coverage of subject areas and techniques by providing a sample course format. (JN)

Describes the nature and capabilities of methods used to characterize protein and peptide structure, indicating that they have undergone changes which have improved the speed, reliability, and applicability of the process. Also indicates that high-performance liquid chromatography and gel electrophoresis have made purifying proteins and peptides a…

Possible modes of food deterioration (such as microbial decay, nonenzymatic browning, senescence, lipid oxidation) are reviewed. A basic mathematical approach to the kinetics of food deterioration, kinetic approach to accelerating shelf-life deterioration, and shelf-life predictions are discussed. (JN)

Describes an experiment in which the reaction rate and equilibrium constant are obtained for the fumarase-catalyzed interconversion of fumaric acid and L-malic acid. (MLH)

Discusses the copper-containing molecule that carries oxygen to the tissues of animals in the phyla mollusks and arthropods. (MLH)

Discusses the use of drugs in controlling human behavior, referring particularly to problems associated with applying results from animal experiments to humans, the technique of controlled experiments, the biochemistry of behavior, behavioral disturbances, the uses and effects of psycho-drugs, and the questions of ethics and potential abuse. (JR)

Short articles describing a model of protein synthesis, a simple constant temperature incubator, techniques for determining the age structure of populations from qualitative characters, an experimental demonstration of proteolytic enzyme action, and apparatus for demonstrating hydrotrophic response of roots and for measuring photosynthetic rate of…

Describes a chemistry course designed for nursing students, but from which other majors might benefit, which integrates organic and biochemistry. Listed are the course's topics and with a description of how they are treated. Compares students' rank in this course with their rank in biology and general chemistry. Reports student results on the ACS…

Article rebuts the theory that known sex differences in cognitive abilities reflect sex-related differences in physiology". (Author/ML)

Presents genetical and biochemical data to show that the conclusion presented by Dyer (EJ 036 108) is by no meas settled. Evidence to support the concept: evolution by selectively neutral polymorphisms is inconclusive. (AL)
