Discusses the determination of hydrolyzable amino acid precursors and a group of six amino acids in the returned lunar samples of the Apollo programs. Indicates that molecular evolution is arrested at the precursor stage on the Moon because of lack of water. (CC)

Discusses two pedagogical problems encountered in teaching of inorganic chemistry, namely, excessive instruction of bond theory and neglect of introducing new development, especially bioinorganic knowledge. (CC)

Discusses the atmospheric characteristics of the earth and their implications for the development of life on earth-like planets. Indicates that the chance of life developing on other planets is not as great as men might have thought. (CC)

Describes a workshop on the feasibility of disseminating chemical injurious information through instructional materials. Indicates the necessity of including basic principles in physiology, biology, and environmental courses at both secondary and undergraduate levels. (CC)

Reported was the medical case history of an 11-year-old profoundly retarded boy in which his micropolygyric frontal cortex was found to reveal three chemical changes. (CB)

Topics in this discussion of photorespiration (light-dependent oxygen consumption and carbon dioxide evolution from leaves) include: (1) the biochemistry of photorespiration; (2) ribulose biphosphate carboxylase and glycollate synthesis; (3) metabolism of glycollate; (4) plants lacking photorespiratory systems; and (5) advantages of…

The syllabus for a refresher course on the physiology and biochemistry of receptors (presented at the 1983 American Physiological Society meeting) is provided. Topics considered include receptor regulation, structural/functional aspects of receptors for insulin and insulin-like growth factors, calcium channel inhibitors, and role of lipoprotein…
