In the sixteenth century, Paracelsus added some mineral compounds to the Materia Medica and powerful medicines were obtained from the ores of metals like mercury and antimony by alchemical processes. Antimony has a very long history in medicine, but it came into greater prominence at a critical time in the sixteenth century when syphilis, then a new killer disease, was rapidly spreading across Europe.5 Paracelsus mercurial preparations were also effective, although their poisonous 

Chemical theories in medicine were not confined to the diagnosis and treatment of disease, for it was gradually realized that normal physiological functions such as 

Copper-Containing Enzymes in Oxygen Activation and Reduction Mars and Venus — The Role of Copper in Iron Metaholism 

Copper is present in a large number of enzymes, many involved in electron transfer, activation of oxygen and other small molecules like oxides of nitrogen, methane and carbon monoxide, superoxide dismutation, and even, in some invertebrates, oxygen transport (for further details see Granata et al., 2004 Hatcher and Karlin, 2004 Messerschmidt et al., 2001 Rosenzweig and Sazinsky, 2006 Solomon, 2006).

In Cu-containing proteins, three types of Cu centres are found, classified on the basis of their visible, UV, and EPR spectra, as originally proposed by one of the pioneers of Cu biochemistry. Bo Malmstrom (Malkin and Malmstrom, 1970). Types 1 and 2 centres have a single Cu atom which has an intense blue colour in Type 1 centres, but the single Cu atom in Type 2 centres is almost colourless. In contrast. Type 3 centres have a di-Cu centre which is EPR-silent. More details of the three types are given below

The basic structure of carotenoids is a conjugated polyprenoid chain. Carotenoids exert a positive impact on human welfare. They show marked singlet molecular oxygen quenching capacity [11] and they protect against photosensitized peroxidation of lipids [12],

Free energy perturbation (FEP) theory is now widely used as a tool in computational chemistry and biochemistry [91]. It has been applied to detennine differences in the free energies of solvation of two solutes, free energy differences in confonnational or tautomeric fonns of the same solute by mutating one molecule or fonn into the other. Figure A2.3.20 illustrates this for the mutation of CFt OFl CFt CFt [92].

A particular mode of neurotoxicity was discovered for tricresyl phosphate that correlated with the presence of the o-cresyl isomer (or certain other specific aLkylphenyl isomers) in the triaryl phosphates. Many details of the chemistry and biochemistry of the toxic process have been elucidated (139,140,143—146). The use of low ortho-content cresols has become the accepted practice in industrial production of tricresyl phosphate. Standard in vivo tests, usually conducted with chickens sensitive to this mode of toxicity, have been developed for premarket testing of new or modified triaryl phosphates. As of 1992, the EPA called for extensive new toxicity and environmental data on this group of products (147). The Vederal e ster AoQ xm. ci. calling for this... 

Forensic science is an applied science having a focus on practical scientific issues that come up during criminal investigations or at trial. Some components ate unique to the field because it is conducted within the legal arena. Forensic science issues in chemistry and biochemistry in criminal investigations are discussed herein. There are a host of other forensic science areas, eg, forensic medicine, forensic dentistry, forensic anthropology, forensic psychiatry, and forensic engineering, any of which may overlap with forensic chemistry. 

Immunoassay is a method that identifies and quantifies unknown analytes usiag antibody—antigen reactions. Techniques are based ia immunochemistry, analytical chemistry, and biochemistry, with a history of development paralleling advances ia microbiology and immunology (see also Immunotherapeutic agents).

Selenium also forms a large number of organic compounds. Of special interest are the oxidizing and reducing actions of selenium and its compounds. Chemical reactions are described in detail elsewhere (1 9). Organic reactions are reviewed in References 10 and 11. The organic chemistry and biochemistry of selenium is also available (12—16). 

Free thiocyanic acid [463-56-9] HSCN, can be isolated from its salts, but is not an article of commerce because of its instabiHty, although dilute solutions can be stored briefly. Commercial derivatives of thiocyanic acid are principally ammonium, sodium, and potassium thiocyanates, as weU as several organic thiocyanates. The chemistry and biochemistry of thiocyanic acid and its derivatives have been reviewed extensively (372—374).

The role of oceanic physical chemistry and biochemistry in the enhanced greenhouse future is still uncertain. We have discussed the mechanisms generating a number of potential feedbacks, both positive and negative in their impact. However, new interactions are constantly being discovered in nature, and model representation of them is a rapidly evolving science. At present what we can say is that this is a young field of much intellectual and practical promise. 

Many methods exist for the purification of reagents and solvents. A number of these methods are routinely used in synthetic as well as analytical chemistry and biochemistry. These techniques, outlined below, will be discussed in greater detail in the respective sections in this Chapter. It is important to note that more than one method of purification may need to be implemented in order to obtain compounds of highest purity. 

Basicity and acidity are fundamental and familiar concepts in chemistry and biochemistry. Quantum chemistry has provided a theoretical understanding of the phenomena as far as the gas phase in concerned. However, it is known that in solution reactivity is seriously affected by solvents. One example of such a well-known phenomenon is that the basicity...
