In nature, amino acids are found in two forms, L and D enantiomers, except for glycine which
does not have a chiral center. The change of one form to the other will lead to a change in …

Ion mobility spectrometry (IMS) is gaining importance in the field of food safety and
authenticity in recent years due to its main potential to overcome the challenges that arise …

Liquid chromatography–mass spectrometry (LC–MS) delivers sensitive peptide analysis for
proteomics but requires extensive analysis time, reducing throughput. Here, we demonstrate …

In recent years, ion mobility spectrometry-mass spectrometry (IMS-MS) has advanced the
field of omics-based research, especially with the development of high-resolution platforms; …

Recently, ion mobility spectrometry‐mass spectrometry (IMS‐MS) has become more readily
incorporated into various omics‐based workflows. These growing applications are due to …

Synthetic cannabinoids, a subclass of new psychoactive substances (NPS), are laboratory-
made substances that are chemically similar to those found naturally in the cannabis plant …

Tandem mass spectrometry of denatured, multiply charged high mass protein precursor ions
yield extremely dense spectra with hundreds of broad and overlap** product ion isotopic …

Plaques that characterize Alzheimer's disease accumulate over 20 years as a result of
decreased clearance of amyloid-β peptides. Such long-lived peptides are subjected to …

Characterization and monitoring of post-translational modifications (PTMs) by peptide
map** is a ubiquitous assay in biopharmaceutical characterization. Often, this assay is …

Life was originally assumed to utilize the l-amino acids only. Since 1980s, the d-amino acid-
containing peptides (DAACPs) were detected in animals, often at extremely low levels with …
