The home page explains the role of the committees and lists its publications, including a WWW full-text version of the recommendations on amino-acid and peptide nomenclature, on steroid nomenclature, on carbohydrate nomenclature and on enzyme nomenclature (see below). Further WWW versions of other recommendations will be added as soon as they can be prepared.
There is also a link to the electronic submission form for suggested new enzymes to be assigned an EC number and added to the list . A link to the separate form for submitting corrections to any of the published enzymes is also included.
Information is provided on the membership of the committees, their specialist interests and e-mail addresses, as well as the parent bodies.
Nomenclature and symbolism for amino acids and peptides. Recommendations 1983  and Nomenclature of steroids. Recommendations 1989 . The third edition of each of these nomenclature recommendations was published several years ago. Copies of these recommendations are now available via the Internet and are exactly the same as the published versions subject to modifications due to the current limitations in programming WWW pages. Since the original publications, a number of extensions have been published in the committees newsletters and reprinted in the Compendium . In the WWW versions, the additions form an addendum which has been linked to appropriate places in the main text. All corrections to the printed versions of these documents have been flagged and details listed. These documents can be accessed from the committees home page or directly at
Nomenclature of carbohydrates. Recommendations 1996 and the three Supplements to Enzyme Nomenclature 1992 , together with all enzymes of subclass EC 3.4 (peptidases), can also be accessed directly at
