Early Stage Detection Of Marine Oil Oxidation, Loren Lapointe
Honors Theses
A method involving overnight stir bar sorptive extraction (SBSE) headspace gas chromatography/mass spectrometry (GC/MS) in negative ion chemical ionization (NICI) mode was developed to determine the presence of aldehydes (cis-4-heptenal, trans,trans-2,4-heptadienal, trans-2-octenal, cis-6-nonenal, trans-2-cis-6-nonadienal, trans-2-nonenal, and trans,trans-2,4-decadienal) in fresh and aged commercial fish oil (untreated and treated with antioxidant blends). Aldehyde standards were quantifiable to >100ppb levels using this method. Only trans,trans-2,4-heptadienal was shown to be present in the commercial fish oil and its presence was used to compare the performance of the two different antioxidant treatments in the fish oil. Includes Powerpoint.

Stability Of Eukaryotic Elongation Factor One Alpha Protein In The Cell, Jennifer Watry
Honors Theses
Eukaryotic Elongation Factor One Alpha (eEF1A) is an abundant protein found in every cell of every organism and is involved in functions concerning protein synthesis and degradation, the cytoskeleton, and signaling. How these functions are regulated is not yet understood for this protein. Regulation of the protein may be controlled by transcription of the genes encoding the protein or the stability and modification of the protein. The goal of this project was to determine the stability of eEf1A proteins in Arabidopsis thaliana. Protein stability was determined by treating tissues with cycloheximide, an inhibitor of protein synthesis. Gel electrophoresis and …
