Derived plant and animal products make better use or upgrade the nutritional quaHty of already existing materials or products. Synthetic and manufactured products arose from knowledge of the functional properties of food ingredients and of human and animal nutrition that involved more precise definition of nutrient requirements for growth, reproduction, lactation, and body maintenance in both humans and domestic Hvestock. Pood products have been developed to meet human needs under abnormal environments, eg, military rations for arctic, tropical, or desert environments, and special products for astronauts ia space flights.

The abihty to remove heat from electrophoretic systems has severely limited the maximum capacity of these systems in terms of how large or thick the systems can be. Electrophoretic separations have been performed on space flights because the effect of gravity in outer space is small and mixing from heating is negligible. Whereas electrophoresis in outer space has been accompHshed (10), the economics for a scaleable process have not (see Space processing).

MSA are under development at the NASA s Goddard Space Flight Center, and has been selected to be the multi-slit device for NIRSpec. They use a combination of magnetic effect for shutter opening, and electrostatic effect for shutter latching in the open position (Moseley et al., 2002).

Now consider the hypothetical problem of trying to teach the physics of space flight during the period in time between the formulation of Kepler s laws and the publication of Newton s laws. Such a course would introduce Kepler s laws to explain why all spacecraft proceed on elliptical orbits around a nearby heavenly body with the center of mass of that heavenly body in one of the focal points. It would further introduce a second principle to describe course corrections, and define the orbital jump to go from one ellipse to another. It would present a table for each type of known spacecraft with the bum time for its rockets to go from one tabulated course to another reachable tabulated course. Students completing this course could run mission control, but they would be confused about what is going on during the orbital jump and how it follows from Kepler s laws. 

The principles of Kepler s laws and orbital jumps in isolation would leave students confused. Alternatively suppose students were taught that only free-falling space flight can be understood from Kepler s laws, and that the tables for course corrections had been constructed from careful experimentations and observations. In this case, students would not be confused either. The confusion comes from stating that everything will be explained theoretically and then only explaining half.

The fields of application of analytical chemistry extend from research to service, diagnosis, and process control, from science to technology and society, from chemistry to biology, health services, production, environmental protection, criminalogy and law as well as from chemical synthesis to materials sciences and engineering, microelectronics, and space flight. In brief, analytical chemistry plays an important role in every field of our life.

There are many excellent texts on nutrition. This chapter, therefore, focuses not on nutrition per se but on how biochemistry helps us understand well established and less well established aspects of nutrition and how such knowledge fits in with other subjects discussed in this text. There is now considerable medical and lay interest in what is meant by healthy and unhealthy diets. Nutrition has become a major issue in the medical sciences and in clinical practice. It is also of concern to politicians, particularly in the link between nutrition and Western diseases such as cardiovascular disease, obesity, cancer and neurological problems. In this chapter an attempt is made to provide a biochemical basis for discussion of nutrition and development of these conditions. To this end, biochemical explanations for nutritional advice and the recommendations from national bodies are provided. Similarly, explanations for the recommendations designed for different populations, different conditions and activities (physical and mental activity, the elderly, the young, during pregnancy and space flight) are discussed. Finally, the biochemistry of malnutrition, undemutrition and ovemutrition is discussed.
