Webprotein. The ionizable group will be influenced by the chemical structure and partial charges (dipoles), but not by charge–charge interactions, or to a great extent by burial. … Web1 dag geleden · Methyl-coenzyme M reductase, responsible for the biological production of methane by catalyzing the reaction between coenzymes B (CoBS-H) and M (H3C-SCoM), hosts in its core an F430 cofactor with the low-valent NiI ion. The critical methanogenic step involves F430-assisted reductive cleavage of the H3C–S bond in coenzyme M, yielding …
http://english.dicp.cas.cn/news/rn/201401/t20140122_315323.html Chemical ionization (CI) is a soft ionization technique used in mass spectrometry. This was first introduced by Burnaby Munson and Frank H. Field in 1966. This technique is a branch of gaseous ion-molecule chemistry. Reagent gas molecules (often methane or ammonia) are ionized by electron ionization to form … Meer weergeven The chemical ionization process generally imparts less energy to an analyte molecule than does electron impact (EI) ionization, resulting in less fragmentation and usually a simpler spectrum. The amount of fragmentation, … Meer weergeven The CI source design for a mass spectrometer is very similar to that of the EI source. To facilitate the reactions between the … Meer weergeven One of the main advantages of CI over EI is the reduced fragmentation as noted above, which for more fragile molecules, results in a peak in the mass spectrum indicative of the molecular weight of the analyte. This proves to be a particular advantage … Meer weergeven Negative chemical ionization Chemical ionization for gas phase analysis is either positive or negative. Almost all neutral analytes can form positive ions through the … Meer weergeven A CI experiment involves the use of gas phase acid-base reactions in the chamber. Some common reagent gases include: methane Meer weergeven CI mass spectrometry is a useful tool in structure elucidation of organic compounds.
