Differential 15N2-/14N2-isotope Dansylhydrazine Labeling and LC-MS for Quantification of the Human Carbonyl Metabolome
DownloadFall 2011
The objective of this work was the design and use of paired labeling reagents that are chemically identical but isotopically different to provide a simple and robust means of quantitative mass spectrometry (MS) based metabolome profiling. Herein is presented the differential 15N2-/14N2-isotope...

Functional and topological analysis of yeast acyl-CoA:diacylglycerol acyltransferase 2, an endoplasmic reticulum enzyme essential for triacylglycerol biosynthesis
Download2011
Siloto, Rodrigo M. P., Snyder, Crystal L., Liu, Qin, Weselake, Randall J.
Acyl-CoA:diacylglycerol acyltransferase (EC 2.3.1.20) is a membrane protein present mainly in the endoplasmic reticulum. It catalyzes the final and committed step in the biosynthesis of triacylglycerol, which is the principal repository of fatty acids for energy utilization and membrane...

Fall 2013
High throughput bio-technologies in chemistry experiments generate a huge amount of data. These data are awaiting to be analyzed for knowledge discovery. In this work, we have developed a web-based resource MyCompoundID for compound identification. Our base database contains 8,021 metabolite...

Spring 2022
Background: In metabolic disease statues, such as diabetes and obesity, dyslipidemia is characterized by a dysregulation of lipid homeostasis, due in part to elevated triglyceride (TG)-rich very low-density lipoprotein (VLDL-TG) production and secretion by the liver. Further, these metabolic...

In-line Ozonolysis coupled to Mass Spectrometry- A New Dimension of Structural Determination for Lipids
DownloadFall 2014
The location of double bonds within unsaturated lipids can greatly affect their biological functions. Liquid chromatography coupled to mass spectrometry (LC/MS) has become a powerful tool for lipid separation and structural elucidation. However, the determination of double bond position remains...

Insulin and testosterone are associated with elevated intestinal secretion of lipids and lipoproteins in a rodent model of the metabolic and polycystic ovary syndrome
Download2014
Wang, Ye, Shi, Danni, Proctor, Spencer D., Vine, Donna F.
The metabolic syndrome is highly associated with the incidence of Polycystic Ovary Syndrome (PCOS). The metabolic aberrations of insulin resistance and hyperandrogenemia have been proposed to contribute to the development of dyslipidemia and increased Cardiovascular Disease (CVD) risk in PCOS....

Investigating Protein-Carbohydrate Interactions with Hydrogen/Deuterium Exchange Mass Spectrometry (HDX-MS)
DownloadFall 2014
The application of hydrogen/deuterium exchange mass spectrometry (HDX-MS) to investigating protein-carbohydrate interactions is described. Proteins from three bacterial toxins, the B subunit homopentamers of Cholera toxin (CTB5) and Shiga toxin type 1 (Stx1B5) and a fragment of Clostridium...

Isotope Labeling Liquid Chromatography Mass Spectrometry: Metabolite Identification and Human Salivary Metabolome Profiling
DownloadFall 2012
The objective of this work was to use paired labeling reagents that are chemically identical but isotopically different to provide a simple and robust way of mass spectrometry (MS)-based metabolome profiling. A differential 13C-/12C-isotope dansyl chloride (DnsCl) derivatization strategy has been...

J-Coupling Effects on Quantification of the 1.3 ppm Lipid Methylene Resonance with In-Vivo Magnetic Resonance Spectroscopy at 3 T
DownloadFall 2015
Quantification of 1.3 ppm lipid methylene protons by proton magnetic resonance spectroscopy has been shown to be relevant to a number of diseases. Additionally, T2 estimation of 1.3 ppm methylene protons has been used to grade the metastatic potential of colon tumours. J-coupling...
