Described is the first part of a two-term project involving final-year students in biochemistry. Listed are the required experiments compiled to test students' abilities to search biochemical literature, extract experiments from journals and carry them out, generate data, and interpret results. (CS)

An explanation of the difference between the terms isosmotic and isotonic, and an experiment to demonstrate this difference are presented. (BB)

This teacher's guide provides information and resources for helping to familiarize students with chemistry and its everyday applications around the world using inquiry and investigations. Contents include: (1) "Introducing Molecules in Living Systems"; (2) "Considering Life Processes"; (3) "Understanding the Structure of Biomolecules"; (4)…

Offers four reasons for making biochemistry as an option for satisfying the general education science requirement: (1) scientific skills--objectivity, reasoning, and method; (2) broader perspective; (3) integration of beginning and advanced topics; and (4) relevance. (JM)

Outlines the chemistry of the rapid synthesis of relatively large DNA fragments (100-200 monomers each) with yields exceeding 99 percent per coupling. DNA synthesis methodologies are outlined and a polymer-supported synthesis of DNA using deoxynucleoside phosphoramidites is described with structural formulas. (YP)

Describes a study involving 86 fifth-grade science students to enhance their understandings of basic biological chemistry. Contains a lesson that allows students to build models of atoms and molecules. (ZWH)

Described is the use of fluorometry in an experiment where the fluorescence of riboflavin is specifically quenched when titrated with riboflavin-binding protein. The amount of riboflavin, required by all organisms, in an unknown solution and the dissociation constant of the vitamin-protein complex can be determined using this method. (KR)

Describes a set of biochemistry laboratory experiments in which tetrameric hemoglobin is separated into its subunits then formed again by recombination of the subunits. (MLH)

Describes an interdisciplinary course providing basic background in behavior, pharmacology, neuroanatomy, neurotransmitters, drugs, and specific brain disorders. Provides rationale, goals, and operational details. Discusses a research project as a tool to improve critical evaluation of science reporting and writing skills. (JM)

Describes a method, using simple algebraic notation, for calculating the nature of the salient features of a sugar pyranoid ring, the steric disposition of substituents about the reference, and the anomeric carbon atoms contained within the ring. (CS)

Considers various aspects of bee stings including the physical mechanism of the venom apparatus in the bee, categorization of physiological responses of nonprotected individuals to bee sting, chemical composition of bee venom and the mechanisms of venom action, and areas of interest in the synthesis of bee venom. (CS)

Describes the separation of proteins from bovine serum and egg-white using carboxymethyl cellulose, Vistec C1. Explains the preparative work that is essential before the technique can be employed. (GS)

Describes an exercise that illustrates the synthesis of an amino acid and Michael type condensation. The exercise can be used with college students of chemistry or biochemistry. (HM)
