The location of double bonds (C=C) in lipids is determined by their biosynthetic pathways and it can be used to reveal metabolic alterations in biological systems…

Proteoforms are the key effectors in human health and disease. Understanding proteoform distributions in human tissues is critical to pathogenic studies and therapeutics. Imaging mass spectrometry (IMS) is a powerful technique for mapping proteins in tissues…

Post-translational modifications (PTM) affect protein structure, activity, transport and function. The presence of PTMs and their dynamic response to conditions dramatically increases the complexity and versatility of the proteome beyond what can be predicted based on the known protein-coding genes…
