Identification of Unknown Compounds « on: March 30, 2016, 10:37:46 AM » Hi everybody,I'm new here. So I have this experiment that I am doing. I am given an unknown with 2 compounds in it. But I'm not sure whats in the compound. The compound looks like it has both liqui...
unknown compound correctly. Be sure to note where the unknown is a single compound or a mixture. If your unknown is a single compound, you can apply the tests described in the background information in any order that you wish. If your unknown is a mixture of two compounds, you must ...
The unknown compound is acquired in MS/MS mode albeit using high collision energy. After the acquisition, the two MS/MS spectra of unknown and mass calibrator are combined, and the fragments of the unknown are lock mass corrected by using the protonated molecule of the mass calibrator. To ...
An entomopathogenic bacterium, Xenorhabdus nematophila , is known to have potent antibiotic activities to maintain monoxenic condition in its insect host for effective pathogenesis and ultimately for optimal development of its nematode symbiont, Steinernema carpocapsae . In this study we assess its antiba...
Compound libraries such as PubChem or KEGG describe a larger number of compounds, which can be used to compare their in silico fragmentation with spectra of unknown metabolites. Results We created the MetFrag suite to obtain a candidate list from compound libraries based on the precursor mass, ...
Presents a sequence of procedures for identifying an unknown organic liquid using mass, NMR, IR, and UV spectroscopy, along with specific examples of unkno... CA Cerami 被引量: 178发表: 2013年 Mass Spectrometric Analysis of Exhaled Breath for the Identification of Volatile Organic Compound Biomar...
A Study of the Immunoregulatory Function of TLR3 and TLR4 on Mesenchymal Stem Cells in Ankylosing Spondylitis The pathogenesis of ankylosing spondylitis (AS), an immune-mediated inflammatory disease, remains largely unknown. We previously reported that the immunore... Y Li,L Huang,Z Cai,... -...
Chemical species for identification, for being given compensation by the RF voltages of the mobility for measuring the function as high electric field multiple peak values relevant with compound of the signature unique based on ionic mobility is generated. The detection data of generation compares data...
of macrocyclic archaeol was unexpected, as this lipid has only been detected in a few archaeal species26,27,28. To confirm the structure of the macrocyclic archaeol, we purified this compound fromM. maripaludisexpressingmaeo_0574. We subsequently cleaved the ether groups through an ether cleavage ...
