A discussion of nutrition's role in athletics is presented in this article. The effects of good day-to-day nutrition, the pregame meal, fluid intake, and dietary supplements on the athletes endurance and performance are discussed. (DF)

The search for the meaning of the word shunt as it is used in the hexose monophosphate shunt system is described. A review of the literature on this pathway is included. (KR)

Discusses the physiology and biochemistry of the vitamin D endocrine system, including role of biological calcium and phosphorus, vitamin D metabolism, and related diseases. A 10-item, multiple-choice test which can be used to obtain continuing medical education credit is included. (JN)

Management of insulin dependent diabetes mellitus (IDDM) is a complex task that requires the adolescent with IDDM recognize the interaction between diet, exercise, stress, emotions, and insulin dosage. With regularity, however, adolescents with IDDM are shown to be in less good metabolic control than younger children or young adults. The study…

Reviews current findings that explain RNA's function as an enzyme in addition to being an informational molecule. Highlights recent research efforts and notes changes in the information base on RNA activity. Includes models and diagrams of RNA activity. (ML)

Discusses the biochemical mechanisms related to photosynthesis. Describes a water-oxidizing clock generating a molecule of oxygen with every four ticks. Lists four references. (YP)

Describes an experiment to characterize the enzyme polyphenol oxidase. Includes Purpose, Reagents and Equipment, Procedure, Extraction, Treatment of Data, and Discussion. (MA)

Describes a card game that teachers metabolism to high school biology students. (LS)

Discusses some of the problems associated with teaching abstract concepts in biochemistry because of the inability to provide visual aids. Suggests the use of metabolonograms as analogies in teaching certain concepts. (TW)

Discusses the role of the small intestine in the digestion and absorption of carbohydrates and proteins. Indicates as outdated the view that these materials must be broken down to monomeric units before absorption and that the gut secretes a mixture of digestive juices which brings about absorption. (JN)

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)

A laboratory exercise for dental students is presented using a toxic dose of lidocaine in place of an anesthetic dose of pentobarbital. The use of lidocaine demonstrates its toxic and lethal actions and increases the relevance of the experience for dental students. (Author/MLW)

Information about the biosynthesis of the carbohydrate portions or glycans of glycoproteins is presented. The teaching of glycosylation can be used to develop and emphasize many general aspects of biosynthesis, in addition to explaining specific biochemical and molecular biological features associated with producing the oligosaccharide portions of…

This lesson plan is intended for use in conducting classes on photosynthesis. Presented first are an attention step/problem statement and a series of questions and answers designed to convey general information about photosynthesis. The following topics are among those discussed: the photosynthesis process and its importance, the organisms that…

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)
