Abstract: Abstract Residue-specific cleavages resulting in the formation of [a]+ ions of peptides have been examined using 20 keV high-energy (high-E) collision-induced dissociation (CID) with a tandem time-of-flight (TOF/TOF) instrument. High-E CID resulted in relatively sensitive cleavage… read more here.

DOI: 10.1177/1934578x231175261
Abstract: Dear Editor, It is not yet known why the number of proteinogenic amino acids is limited to 20. Some explanations for this problem have been attempted, but it is still unresolved. Aminomalononitrile is a hydrogen… read more here.

DOI: 10.3389/fnins.2021.664525
Abstract: We retrospectively examined the relationship between blood biomarkers, in particular the historical mean phenylalanine to tyrosine (Phe:Tyr) ratio, and cerebral glucose metabolism. We hypothesized that the historical mean Phe:Tyr ratio would be more predictive of… read more here.
