*  Glycan analysis mass spectrometry - Need a reliable online directory? look no further!
Glycans are compounds that consist of a large number of monosaccharides. Glycans can be homopolymers or heteropolymers of monosaccharide residues and can either be linear or branched. Glycans are found on the exterior surface of cells and can be found attached to proteins as in glycoproteins and proteoglycans. In glycan analysis which seeks to explore the structure and functions of various glycans, high-resolution mass spectrometry (MS) and high-performance liquid chromatography (HPLC) are commonly used.. Mass spectrometry (MS) offers high sensitivity and addresses the most frequent biological issues hence it is a valuable tool for the structural characterization of carbohydrates. Oligosaccharide structures can be explained through mass spectrometry and chromatographic separation derivatization. Some of the techniques used for mass spectrometry are Gas Chromatography coupled to Mass Spectrometry (GC/MS), Liquid ...

*  Atomic mass constant - Wikipedia
In physics and chemistry, the atomic mass constant, mu, is one twelfth of the mass of an unbound atom of carbon-12 at rest and in its ground state. It serves to define the atomic mass unit and is, by definition, equal to 1 u. The CODATA recommended value is 6973166053904000000♠1.660539040(20)×10−27 kg. In practice, the atomic mass constant is determined as the ratio of the electron rest mass me to the electron relative atomic mass Ar(e) (that is, the mass of the electron on a scale where 12C = 12). The relative atomic mass of the electron can be measured in cyclotron experiments, while the rest mass of the electron can be derived from other physical constants. m u = m e A r ( e ) = 2 R ∞ h A r ( e ) c α 2 {\displaystyle m_{\rm {u}}={\frac {m_{\rm {e}}}{A_{\rm {r}}({\rm {e}})}}={\frac {2R_{\infty }h}{A_{\rm {r}}({\rm {e}})c\alpha ^{2}}}} The current ...

387467783 - EP 0898297 A3 2001-01-03 - Methods and apparatus for tandem mass spectrometry - [origin: EP0898297A2] The invention provides methods and apparatus for tandem mass spectrometry (MS/MS) in which parent ions generated from a sample are passed through a mass filter (2) and are fragmented into daughter ions in fragmentation means (3), the daughter ions being passed through a discontinuous output mass analyser, such as a time-of-flight analyzer (16) or an ion storage device (29). The range of possible parent mass-to-charge ratios is split into a plurality of smaller ranges, and the mass filter (2) is set to pass ions of each smaller range in turn. A flag is set for each smaller range which produces daughter ions of interest, and the mass filter (2) is set to pass each mass-to-charge ratio of the flagged ranges so that the mass-to-charge ratios of the ...

*  Atomic mass units | Physics Forums - The Fusion of Science and Community
Been many years since I took general and org chem and am currently reading general chem textbook as refresher. Came across defintion of amu (atomic mass unit). Text says that the mass of the carbon-12 atom is defined to be exactly 12 amu. However, a couple of pages over, I read that the mass of the proton is about 1.007 amu, and the mass of the neutron is about 1.009 amu. Add up the masses of 6 protons and 6 neutrons for the carbon-12 atom, and you come up with more than 12 amu. I can't resolve this apparent discrepancy. I've consulted other texts, etc. Does some type of relativistic effect bear on this situation? In other words, does, for example, an isolated proton have a mass of 1.007 amu, but then when part of an atom have a slightly different mass because of some relativistic effect? HELP ...

Abstract : Butylatedhydroxytoluene (BHT) and 4-methoxyphenol (4-MP) are phenol derivatives that are generally knownfor their antioxidant properties and depigmenting activities. The aim of this study was to evaluate the impact ofbiofield energy treatment on the isotopic abundance in BHT and 4-MP using gas chromatography-mass spectrometry(GC-MS). BHT and 4-MP samples were divided into two parts: control and treated. The control group remaineduntreated while the treated group was subjected to Mr. Trivedi's biofield treatment. Control and treated sampleswere characterized using GC-MS. The GC-MS data revealed that the isotopic abundance ratio of 13C/12C or 2H/1H(PM+1)/PM and 18O/16O (PM+2)/PM increased significantly in treated BHT and 4-MP (where PM- primary molecule,PM+1- isotopic molecule either for 13C or 2H and PM+2 is the isotopic molecule for 18O). The isotopic abundance ratioof (PM+1)/PM in the treated BHT and 4-MP was increased up to 181.27% and 380.73% respectively as comparedto their ...

*  Development and Application of Mass Spectrometry-Based Approaches for Thermodynamic Analysis of Protein-Ligand Binding...
The characterization of protein stability changes and protein-ligand interactions on the proteomic scale is important for understanding the biology of cellular processes. The identification and quantification of protein-ligand binding affinities is critical for disease state analyses and drug discovery. A mass spectrometry-based technique, Stability of Proteins from Rates of Oxidation (SPROX), has been established for the thermodynamic analysis of protein stability and protein-ligand interactions. In the first part of this dissertation, a previously published iTRAQ-SPROX protocol is improved by incorporating a filter assisted sample preparation (FASP) protocol to significantly reduce sample loss during the experiment. Also, in order to eliminate methionine as a potential contaminant that can cause signal suppression during LC-MS/MS analysis, TCEP•HCl is used to quench the H2O2 oxidation instead of methionine. This avoids the potential reaction between the free methionine and the iTRAQ ...

Abstract : 2-Aminopyridine (2-AP) and 2,6-diaminopyridine (2,6-DAP) are two derivatives of aminopyridines that act as animportant organic intermediates, mostly used in medicines, dyes and organic sensors. The aim of the study was to evaluate theimpact of biofield energy treatment on isotopic abundance ratios of 2H/1H, 13C/12C, or 15N/14N, in aminopyridine derivativesusing gas chromatography-mass spectrometry (GC-MS). The 2-AP and 2,6-DAP samples were divided into two parts: controland treated. The control sample remained as untreated, while the treated sample was further divided into four groups as T1, T2,T3, and T4. The treated group was subjected to Mr. Trivedi's biofield energy treatment. The GC-MS spectra of 2-AP and 2,6-DAP showed five and six m/z peaks respectively due to the molecular ion peak and fragmented peaks of aminopyridinederivatives. The isotopic abundance ratio of 2H/1H, 13C/12C, or 15N/14N were calculated for both the derivatives and significantalteration was found in the ...
