Presents two alternative teaching approaches to ensure that students become active participants of learning in the biochemistry classroom. Diagrams and rules are provided for using educational playing cards and creating a biochemical comic book. (ZWH)

An approach for rigorously treating the metabolic pathways as a series of progressive levels emphasizing the integration of knowledge at each level is presented. The method stresses the relationship between diverse material and approaches to lend coherence, comprehension, and retention to the study of the metabolic pathways. (JN)

Introduces an approach to teaching amino acids that employs the use of a poem containing information on the structure and properties of amino acids, and of slides illustrating the poem. Student response to the method was positive. (MA)

A single, didactic criterion for the description of all biological macromolecules is proposed. This criterion is applicable to globular, fibrous or mixed proteins, as well as to nucleic acids and lipids or polysaccharides. Specific examples are given for all except lipids and polysaccarides. (KR)

The Briggs-Haldane assumption is used as the basis for the development of a kinetic model for enzyme catalysis. An alternative definition of the steady state and examples of realistic mechanisms are provided. (KR)

Describes an instructional experiment that was designed to illustrate the use of periodate oxidation in sugar analysis, and the consequence that the absorbance of mixtures of non-interacting substances is additive. (TW)

Suggests a new experiment to study the genetic material of eukaryotes. It is based on the rapid growth and interest of the research on chromatin. (TW)

Offers suggestions to aid the biochemistry and molecular biology teacher in enhancing student understanding of a subject that borrows from many other areas of study as well as its own. (ZWH)

Outlines a laboratory exercise that makes use of Beer's Law plots of cysteine constructed at several pH values over a broad range of wavelengths to estimate the tautomeric ratio (R) of two singly charged ionic forms, calculate the microscopic constants, and construct ultraviolet spectra for both light absorbing species. (CW)

Automated evaluation methods, used in medical school training programs, are discussed. The use of situational questions which help students to make connections between the biochemical knowledge acquired and its application in medical practice is proposed. Examples of these types of questions are included. (KR)

Describes two complementary laboratory exercises that use the glass fiber assay to assess receptor specificity and hormone binding affinity in rat liver cytoplasmic extracts. Details the methods, materials and protocol of the experiments. Discusses the basic concepts illustrated and the feasibility of using the experiments at the undergraduate…

Described is a microscale chemistry laboratory in which a dipeptide is synthesized from its component amino acids and analyzed using chiral-phase thin-layer chromatography. Experimental procedures, and materials are discussed. Twelve references are listed. (CW)

Reviews current biochemistry, education, and polymer course options found in chemistry programs. Proposes a new core curriculum with 28 semester hours with courses in inorganic, chemical, and instrumental analysis, organic, bioorganic, and physical chemistry. Notes that the new curriculum would better prepare students for the existing employment…

The idea that errors and misconceptions in biology textbooks are often slow to be discovered and corrected is discussed. Selected errors, misconceptions, and topics of confusion about cell metabolism are described. Fermentation, respiration, Krebs cycle, pentose phosphate pathway, uniformity of catabolism, and metabolic pathways as models are…

An experiment that uses the recombinant plasmid pX1108 to illustrate restriction mapping is described. The experiment involves three restriction enzymes and employs single and double restriction enzyme digestions. A list of needed materials, procedures, safety precautions, results, and discussion are included. (KR)
