October Update

I am done with collecting data on the tetrapeptides containing lysine homologs. I am also done with aspargine and its methyl ester and glutamine methyl ester. However, I am still doing h/d exchange with glutamine to collect better data. I start to focus on the asaparagine tetrapeptides again. Recently, on of my lab peers synthesized…

September Updates

September consisted of performing hydrogen/deuterium exchange (h/d exchange) on b2+ ions of the lysine (and its homologs) tetrapeptide(s). I believe I have conducted enough research on these peptides, but I will look back at the data work up to see if there is a need to redo some data collection. The summer research showcase happened,…

August Update

For the my last week in Williamsburg, I continued to perform hydrogen/deuterium exchange (h/d exchange) on b2+ ions of the lysine (and its homologs) tetrapeptide(s), and h/d exchanage with aspargine and glutamine and their methyl esters. In addition, I worked up calculations of the rate of h/d exchanges before I left. The rest of this…

July Update

I am still performing hydrogen/deuterium exchange (h/d exchange) on tetrapeptides of lysine, lysine homologs, and arginine. I am continuing to looking into the h/d exchange of b2+ ions of the lysine (and its homologs) tetrapeptide(s), and may possibly look into the b3+  ions. I am also performing h/d exhcnage with aspargine and glutamine and their…

June Update

I am currently performing hydrogen/deuterium exchange (h/d exchange) on lysine tetrapeptides of XAAA, which X is lysine or its homolog, and A is alanine. I am also looking into the h/d exchange of b2+ ions of these tetrapeptides. However, there is still a lot of necessary adjustments and testing varying mass spectrometer parameters in order…
