Chiral Chromatography. Chiral chromatography is used for the analysis of enantiomers, most useful for separations of pharmaceuticals and biochemical compounds (see Biopolymers, analytical techniques). There are several types of chiral stationary phases those that use attractive interactions, metal ligands, inclusion complexes, and protein complexes. The separation of optical isomers has important ramifications, especially in biochemistry and pharmaceutical chemistry, where one form of a compound may be bioactive and the other inactive, inhibitory, or toxic. 

Paracelsus, a Swiss physician of the sixteenth century, stated that everything is toxic, it is just the dose that matters. This statement still holds true 500 years after Paracelsus developed it to defend the use of toxic compounds such as lead and mercury in the treatment of serious diseases such as syphilis. Chemical compounds cause their toxic effects by inducing changes in cell physiology and biochemistry, and an understanding of cellular biology is a prerequisite if one wishes to understand the nature of toxic reactions.

The biochemistry and taxonomy of cereals is relevant to their potential differential toxicity. The proteins in the cereal grains known as "gluten activate celiac disease. Gluten is a complex mixture of hundreds of related but distinct proteins. The grains considered capable of producing adverse effects in individuals with celiac disease include different species of wheat (e.g., durum, spelt, kamut), barley, rye, and their cross-bred hybrids (e.g., triticale, which is a cross between wheat and rye) (Ciclitira et ah, 2005 Cornell et ah, 2002 Dewar et ah, 2006 Howdle, 2006 Koning, 2008 Lester, 2008 Moron et ah, 2008 Thompson, 2000, 2001 Troncone et al., 2008a Vader et ah, 2003 Wieser and Koehler, 2008). 

The biochemistry of iron has just been discussed in some detail including the biochemical species involved, bioaccumulation, transport, storage, and toxicity- Space does not permit an extensive discussion of other elements of importance. However, a brief discussion will be presented here with a table summarizing what is currently known. 

How do chemical analyses of foods differ from analyses used in chemistry, biochemistry and biology The same methods and techniques are often used only the purpose of the analysis may differ. But foods are to be used by people. Therefore, methodology to determine safety (presence of dangerous microbes, pesticides, and toxicants), acceptability (flavor, odor, color, texture), and nutritional quality (essential vitamins, minerals, amino acids, and lipids) are essential analyses. Current Protocols in Food Analytical Chemistry is designed to meet all these requirements.

Ultimately, most environmental pollutants and hazardous substances are of concern because of their effects on living organisms. The study of the adverse effects of substances on life processes requires some basic knowledge of biochemistry. Biochemistry is discussed in this chapter, with an emphasis on the aspects that are especially pertinent to environmentally hazardous and toxic substances, including cell membranes, deoxyribonucleic acid (DNA), and enzymes.
