This enzyme [EC 5.3.1.1], also known as triosephosphate mutase (TIM) and phosphotriose isomerase, catalyzes the interconversion of D-glyceraldehyde 3-phosphate and dihydroxyacetone phosphate (fUPAC glycerone phosphate). As pointed out by Rose, this enzyme is chiefly responsible for the largely symmetrical conversion of the two three-carbon segments of glucose to lactate and for the nearly uniform distribution of from pyruvate in the glucosyl units of hver glycogen. The... 

Latin name for the German stale of Hessen where the institute is located. There was an element naming controversy as to what the elements from 101 to 109 were to be called thus FUPAC adopted unniluclium (symbol Unot as a temporary name for this element In 1994 a committee of IUPAC recommended that element 108 be named hahnium. The name hassiunt was adopted internationally, however, in 1997. 

Lactams Cyclic amides are called lactams. Lactams are formed from amino acids, where the amino group and the carboxyl group have joined to form an amide. Lactams are named like lactones, by adding the term lactam at the end of the fUPAC name of the parent acid. Common names of lactams are formed by changing the -ic acid ending of the amino acid to -olactam. 

Punctuation is important when writing fUPAC names. fUPAC names for hydrocarbons are written as one word. Numbers are separated from each other by commas and are separated from letters by hyphens. There is no space between the last named substituent and the name of the parent alkane that follows it. 

To summarize and amplify these rules, we take the following steps to find an acceptable fUPAC name for an alkane ...

Resolving Power and Resolution In Mass Spectrometry The resolving power of a mass spectrometer describes the smallest mass differences which can be separated by the mass analyser (Webb, 2004b). Resolution and resolving power in MS today are defined differently depending on the analyser or instrument type, and is often stated without the indication of the definition employed. The new fUPAC definitions of terms used in MS provide a precise definition.
