Presents five questions with answers regarding chemistry and living systems and ecology. (RH)

Describes a biochemistry program at the University of Lancaster designed to emphasize the need for thinking clearly and persevering through a problem. (GS)

Describes a biochemistry experiment involving the kinetics of passive diffusion of solutes across artificial membranes formed by dispersing phospholipids in aqueous medium. (MLH)

Discusses various theories about life on Mars and biochemical experiments pertaining to the origin of life. (MLH)

Trace elements and some drugs can be identified in hair and it seems likely that other organic chemicals will be identifiable in the future. Since hair is so easily collected, stored, and analyzed it promises to be an ideal complement to serum and urine analysis as a diagnostic tool. (BB)

Experiments are described in which inhibitors are used to investigate the timing of transcription and translation of the messenger RNA for the enzyme invertase. It is suggested that plant tissue slices provide adaptable material with which to study enzyme induction, protein synthesis, and cell differentiation at sixth-form level. (Author/MA)

Presents the response of the American Industrial Health Council (AIHC) to the Occupational Safety and Health Administration's (OSHA's) genetic proposal for regulating chemical carcinogens in industry. (HM)

Reviews the chemistry of nerve cells. (SL)

Presents an evolutionary scheme for the physical, chemical, and biological origins of life. The molecular factor is the field of analysis. The need for a reconciliation of science and philosophy is indicated. Extensive references are given. (MA)

The syllabus for a one-semester undergraduate course in biochemical education is provided. (CP)

Discusses selected bioinorganic aspects of carbonic anhydrase and describes experiments that will reinforce the students' understanding of the presence and essential role that metal ions have in some biological systems. (SL)

Compares differences in function and behavior of two oxygen-binding proteins, myoglobin found in muscle and hemoglobin found in blood. Describes the mechanism of oxygen-binding and allosteric effect in hemoglobin; also describes the effect of pH on the affinity of hemoglobin for oxygen. (CS)

A one-hour presentation given to veterinary medical students at Texas A&M University during their first week of professional school is summarized. It helps the students place some of their subjects and disciplines in perspective, emphasizing the overall morphologic organizational scheme of the higher vertebrate body. (LBH)

Describes the nature and action of hematopoietic proteins which regulate the production of specific sets of blood cells. Discusses the production of these hematopoietins by recombinant-DNA methods in an effort to enable physicians to treat patients by eliciting production of specific types of blood cells. (CW)

Discusses the role of zinc in various enzymes concerned with hydration, hydrolysis, and redox reactions. The binding of zinc to protein residues, properties of noncatalytic zinc(II) and catalytic zinc, and the reactions catalyzed by zinc are among the topics considered. (JN)
