Characterization Of Flavonoid Reactivities And Degradation Products Using Online Continuous Flow Kinetic Measurements And Higher Order Mass Spectrometry
(Chemistry & Biochemistry, 2014-03-12)
Epidemiological studies offer strong evidence that diets rich in fruits and vegetables provide a defense against cardiovascular disease, cancer and other physiological disorders. One theory suggests that these hazards are ...
The Use Of Supercritical Fluid Chromatography (sfc) And Liquid Chromatography (lc) For The Separation Of Pharmaceutical Products, Natural Products And Chiral Phosphoric And Sulfonic Acids
(Chemistry & Biochemistry, 2014-03-12)
This dissertation focuses on two chromatographic techniques, supercritical fluid chromatography (SFC) and high performance liquid chromatography (HPLC). The goal of the SFC work is to describe the synthesis of new stationary ...
Dioxygen And Peroxide Activation By An Unnatural Amino Acid Incorporated Cytochrome P450CAM And P450 BM3
(Chemistry & Biochemistry, 2014-03-12)
This study focuses on the process development for a nanobioreactor for the oxidation of aliphatic C-H bond by the dependent activation of molecular oxygen and hydrogen peroxide dependent catalysis of cytochrome P450cam and ...
Design And Synthesis Of Flavin-based Organocatalysts For Biomimetic Aerobic Oxidation Reactions
(Chemistry & Biochemistry, 2014-03-12)
Oxidation reactions are among the most costly and least selective transformations in synthetic chemistry. Catalytic methods that utilize O₂ as a terminal oxidant strive to reduce the inefficiency in this large area of ...
Supporting Traditional Instructional Methods With A Constructivist Approach To Learning: Promoting Conceptual Change And Understanding Of Stoichiometry Using E-learning Tools
(Chemistry & Biochemistry, 2014-07-14)
Stoichiometry is a fundamental topic in chemistry that measures a quantifiable relationship between atoms, molecules, etc. Stoichiometry is usually taught using expository teaching methods. Students are passively given ...
Mechanistic Study Of Cysteine Dioxygenase, A Non-heme Mononuclear Iron Enzyme
(Chemistry & Biochemistry, 2014-09-17)
Cysteine dioxygenase (CDO) is an non-heme mononuclear iron enzymes that catalyzes the O2-dependent oxidation of L-cysteine (Cys) to produce cysteine sulfinic acid (CSA). CDO controls cysteine levels in cells and is a ...
Determination Of Nicotine And Its Metabolites Accumulated In Fish Tissue Using Quechers And Hydrophilic Interaction Liquid Chromatography And Tandem Mass Spectrometry
(Chemistry & Biochemistry, 2014-12)
The quantitative determination of nicotine and its major metabolites (cotinine and anabasine) in fish tissue was performed using hydrophilic interaction liquid chromatography (HILIC) coupled with tandem mass spectrometry. ...
