LC-MS/MS method development for quantitative analysis of cyanogenic glycosides in elderberry and lipid peroxidation products in mice
(University of Missouri--Columbia, 2021)
Cyanogenic glycosides (CNGs) are naturally occurring plant molecules (nitrogenous plant secondary metabolites) which consist of an aglycone and a sugar moiety. Hydrogen cyanide (HCN) is released from these compounds following ...
A study of bacterial cellulose confined ionic liquid and deep eutectic solvent gel materials
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Pollutants have become more prevalent in the air, water, and ground, necessitating the development of technologies that would help, limit, reverse, monitor, measure...
Investigation of the replacement of cysteine residues in DOTA-(Tyr³)-octreotate: synthesis, characterization and evaluation of biological activities
(University of Missouri--Columbia, 2006)
Modification of the peptide sequence of DOTA-Tyr³-octreotate is carried out by substituting the cysteine moieties with D-Cysteine, L-Penicillamine and D-Penicillamine in one or both positions to study the effect of this ...
Design and synthesis of group 8 transition metal complexes for C-C bond forming valorization of carbon dioxide
(University of Missouri--Columbia, 2023)
The abundancy of carbon dioxide (CO2) in Earth's atmosphere combined with its inexpensive cost and low toxicity has made CO2 upconversion to value added products an area of intense interest in catalysis research. While a ...
Studies on the nucleophilic substitution reactions of a dimeric cyclopentadienone
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nucleophilic substitution reactions of 3,5-Dibromo-3a,4,7,7a-tetrahydro-4,7-methano-indene-1,8-dione (48) have been studied. Amines, thiols and alcohols have been employed...
Mixed quantum-classical simulations of intersystem crossing in the exit channel and vibrational adaptive sampling configuration interaction
