International Union of Pure and Applied Chemistry (IUPAC) Nomenclature on World Wide Webb The first of several planned IUPAC nomenclature recommendations have been converted into a World Wide Webb document which can be accessed from your desktop. The "Glossary of class names of organic compounds and reactive intermediates based on structure. Recommendations 1995" [Pure Appl. Chem. 67, 1995, 1307-1375] can now be consulted from: http://www.qmw.ac.uk/~ugca000/iupac.html This contains over 700 class names with over 1300 cross-links and 170 illustrations. Due to the nature of the medium the material is now fully indexed and the entries are ordered into 22 categories so that related material is together. The sections are hydrocarbons, ring systems, alcohols and ethers, aldehydes and ketones, carboxylic acids, compounds with one nitrogen atom, compounds with more than one nitrogen atom, compounds containing boron, halogen, metals, phosphorus arsenic or antimony, silicon or germanium, sulfur selenium or telurium, ions and radicals, natural products and miscellaneous entries. The natural products are subdivided into antibiotics, carbohydrates, lipids, nucleic acids, terpenoids, tetrapyrroles and other natural products. Due to the limitations of the html language some characters have to be converted into text e.g. Greek letters are given as [alpha] etc. However instead of just having a note that a term used in a definition is available elsewhere in the glossary there is now a link. Click on the word and the definition itself will appear. In addition to the glossary there is a full list of nomenclature recommendations from the Commission on the Nomenclature of Organic Chemistry (3.1) and also for the Joint Commission on Biochemical Nomenclature together with those of the Nomenclature Commission of the International Union of Biochemistry and Molecular Biology. There is also a link to the IUPAC data at Cambridge on the organisation of the Union.
