Social and medical research studies are examined that show the dramatic effects of biochemical and nutritional factors on antisocial behavior. They include studies of cobalt levels in hair samples of violent and nonviolent criminals, effects of diet on chronic delinquents, and effects of vitamin/mineral supplements on behaviorally disordered…

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)

Updates knowledge on nitrogen fixation, indicating that investigation of free-living nitrogen-fixing organisms is proving useful in understanding bacterial partners and is expected to lead to development of more effective symbioses. Specific areas considered include biochemistry/genetics, synthesis control, proteins and enzymes, symbiotic systems,…

New advances in molecular biology have established a biotechnology industry and have changed ways people think about living things. In support of this theme, a discussion on historical development and current practice of gene cloning is presented. The role of nucleic acids, viruses, and therapeutic intervention is also considered. (DH)

Discusses the theory of resonance Raman (RR) spectroscopy as it applies to beta-carotene and lycopene pigments (found in tomatoes and carrots, respectively). Also discusses an experiment which demonstrates the theoretical principles involved. The experiment has been tested over a three-year period and has received excellent acceptance by physical…

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)

Describes how a computer simulation is used with a laboratory experiment on the synthesis of urea in isolated hepatocytes. The simulation calculates the amount of urea formed and the amount of ammonium remaining as the concentrations of ornithine, citrulline, argininosuccinate, arginine, and aspartate are altered. (JN)

Provides procedures for synthesizing and purifying a vitamin K metabolite (2,3-epoxide) to introduce many of the techniques used in lipid biochemistry. Includes typical results obtained as well as an optional experiment designed to test the purity of the epoxide obtained. (JM)

Presents some of the basic information on exercise and diet to illustrate biochemical principles. Topic areas include: forms of stored energy; caloric balance, exercise, and weight control; a recommended exercise program; physiological effects of endurance training; and the biochemistry of running a marathon. (JN)

Describes two frequently used DNA sequencing methods: Sander's enzymatic dideoxy method and Maxam and Gilbert's chemical sequencing method. Indicates that studying these methods provides students with knowledge of the chemical structure of DNA and how DNA sequence data are obtained. (JN)

Presents a biochemical overview of the synthesis of food biopolymers that constitute macronutrients in the plant or animal cell. Emphasizes involvement of enzymes in steps characterized by accumulation of materials, activation, polymerization, postpolymerization conversion, and formation of structural components. (JN)

Discusses chemical alterations of selected amino acids resulting from environmental effects (photooxidations, pH extremes, thermally induced effects). Also dicusses use of intentional chemical derivatizations of various functional groups in amino acid residue side chains and how recombinant DNA techniques might be useful in structure/function…

Discusses (1) characteristics, interrelationships, and distribution of food constituents (including water) in unfrozen food systems; (2) the freezing process; and (3) chemical changes in food during frozen storage. Protein alterations and lipid oxidation are emphasized. (JN)

Discusses the relationship of taste and smell to ingestion, digestion, and metabolism. Indicates that the response of these physiological systems can be chemical specific and that chemical senses may play different roles in regulating diet during nutrient deficiency and during nutrient surplus situations. (JN)

Background information, procedures, and results are provided for an experiment in which students: (1) construct an immobilized penicillinase electrode; (2) evaluate electron response as a function of penicillin concentration; and (3) study effects of solvent compositions, ionic strength, and equilibrium time upon electrode response. (JN)
