We describe an inexpensive device for performing capillary electrophoresis (CE) separations with fluorescence detection. As a demonstration of the device's utility we have determined the mass of riboflavin in a commercially available dietary supplement. The device allows for separation of riboflavin in [asymptotically equivalent to] 100 s with a…

Discusses various aspects related to nutrition and athletics. Examines nutritional requirements, energy use, carbohydrate loading, and myths and fallacies regarding food and athletic performance. Indicates that scientific evidence does not validate the use of any special diet by an athlete. (JN)

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)

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)

Surveyed dietetics directors (N=186) and biochemistry instructors (N=153) on topics emphasized in biochemistry courses for dietetics and nutrition students. Results indicate a consistent pattern of variation in topics emphasized and that this variation is influenced by whether students in other major fields are also in a course. (JN)
