Online databases overview

The goal of this chapter is to provide an overview of the occurrence of Type II polyene pheromones and their derivatives, and their chemistry, including their biosynthesis and synthesis. The older literature in this subject area was reviewed in Millar (2000), and summarized more recently in Ando et al. (2004). Thus, this chapter will provide a comprehensive summary of all known Type II pheromone structures and their occurrence in Tables 1 1, whereas the text will focus more on work over the past ten years. The interested reader is further directed to three useful online databases, two of which focus on lepidopteran pheromones (www.tuat.ac.jp/ antetsu/review/e-List.pdf Ando, 2003 www-pherolist.slu. se/pherolist.php Witzgall et al., 2004) and the third of which covers insect pheromones in general (www.pherobase.com El-Sayed, 2008). 

The goal of this chapter is to understand the behavior of ionic liquids as solvents and their influence on reaction based on their chemical structure and microscopic environment. We will therefore provide only a basic overview of their macroscopic physical properties. An online database, compiled by a research team operating under the auspices of the International Union of Pure and Applied Chemists (IUPAC), is now available detailing the physical properties of many known IL species [52],...

The projected, numerical factual database BEILSTEIN-ONLINE represents a natural extension of the Beilstein Handbook of Organic Chemistry which has been published for more than 100 years in more than 300 volumes. The Handbook together with the structure file cards of the literature period 1960-1980 (E-V Period) contain factual and structural information on more than 4 million compounds. The computer representation of organic chemical structures therefore constitutes the centre part of the database design. The chemical structure is described in a post-topological format. Not only constitutional information is included but also a complete stereochemical representation. Bond orders are replaced by electronic information. This allows a much more global and unique representation of tautomers. This paper gives an overview not only of the data structure of chemical compounds but also of its associated physical numerical data and keywords.
