Chirality error in nucleic acid structures
Article Abstract:
An analysis of the Brookhaven Protein Data Bank's nucleic acid structures using a simple program to ascertain their chirality reveals a notable number of errors. Some 34 out of 562 data bank files containing nucleic acid coordinates contained inaccurate configurations of one or more chiral centres. Inconsistencies were also observed in the nomenclature of the amino protons. The study shows that the bank's structures should be tested for adherence to existing stereochemical naming conventions.

The distillation and volatility of ionic liquids
Article Abstract:
Ionic liquids represent matter solely composed of ions, and so are perceived as non-volatile substances. It is shown that some selected families of commonly used aprotic ionic liquids can be distilled at 200-300 degree centigrade and low pressure.
