摘要:

AbstractOrganic ions with high translational energy colliding inelastically with neutral atoms or molecules become excited electronically at the expense of their translational energy. The excitation energy enables a wide range of dissociation reactions to occur and the intensity relationships yield information about the structure of the ions concerned and also permit conclusions to be drawn about the mechanism of their formation.

摘要:

AbstractThe utility and importance of predictive, rather than correlative, molecular orbital calculations in organic chemistry are discussed. Examples of the predictive approach to organic synthesis and the study of organic reaction mechanisms are presented.

摘要:

AbstractBiologically active substances are often effective in nanogram or even smaller quantities. Investigations of their mode of action therefore require highly sensitive microanalytical methods of detection. Chemical, chromatographic or spectrometric methods frequently lack the required sensitivity; it was only after the discovery of the radioimmunoassay (RIA) that quantitative determination of minute amounts of substances in the presence of a millionfold excess of other compounds became possible. The radioimmunoassay combines the extreme sensitivity of detection of radioactively labeled substances with the high specificity of immunological reactions. The superiority of radioimmunological methods over other analytical techniques rests upon their sensitivity, specificity, facile application, and especially their broad general scope.

摘要:

AbstractThe use of chemical methods, and in particular affinity labeling, has greatly advanced our knowledge about the structure of the active sites of ribosomes. Experiments have shown that ribosomal proteins and ribosomal ribonucleic acids participate in the structure of the binding sites for messenger ribonucleic acid and transfer ribonucleic acid.
