Annual Meeting of the ACS Committee on Nomenclature, Terminology and Symbols
`
`New Orleans, National Meeting, Spring 2008
`
`Monday, April 7, New Orleans Marriott Convention Center, River Bend 2 Room, 1.30 PM
`
`Report of the ACS Carbohydrate Division Nomenclature Committee
`
`
`The annual meeting of the IUPAC-IUBMB Joint Commission on Biochemical Nomenclature
`(JCBN) was held in Chevy Chase, MD, May 5--6, 2007 and I hosted the meeting. Following are
`items from that meeting concerning carbohydrate nomenclature, developing from the report I
`delivered last year.
`
`
`Revision of the 1996 Recommendations (2-Carb)
`
`
`Schomburg (JCBN chairman) asked for the status of the revision of the carbohydrate
`nomenclature. Horton said that the 1996 document is over ten years old, but has had small
`corrections incorporated in the web version. He said that there was no urgent reason to do a
`major revision as it covers all areas, including synthetic organic chemistry. Biochemists do not
`need such a detailed document. Instead, they require a more simplified document that addresses
`rapidly developing areas of biochemical interest, such as glycolipids, glycoproteins, and
`glycosaminoglycans. Horton has started the process of producing a carbohydrate document for
`biochemists by removing all material that would be of interest primarily to organic chemists. He
`said that there may still be more information in the document than biochemists would need. He
`suggested that some permitted biochemical usages be included and that the area of
`polysaccharides and glycoproteins may need some amplification by adding examples. The
`document is still at a preliminary stage, but he would appreciate comments and suggestions of
`areas where biochemists do need the information currently contained in the document.
`
`Moss asked if this work comprises two projects rather than one, with the first being a concise
`document for biochemists and the second an update of the carbohydrate document. He pointed
`out that corrections to the 1996 version has been made to the web version but that they need to
`be published. Moss said that he was most concerned with polysaccharides, where the rules for
`naming them are not given and this makes it difficult to name all but the simplest
`polysaccharides. The document also lacks guidance on naming repeating monosaccharides. The
`second document should be covered by a supplement to the 1996 document rather than a
`complete rewrite. Horton, Vliegenthart, McNaught, Dixon and Moss are working on the
`supplement to the 1996 carbohydrate document. This is still underway, and will be discussed
`further at the next JCBN meeting in Copenhagen May 15--16, 2008.
`
`The attention of the meeting was drawn to the Ligraph tool to convert a sugar graph to ASCII
`IUPAC sugar nomenclature. This is available from http://www.glycosciences.de/toolsLiGraph/.
