- Abstract
A defective mucus composition represents a key pathogenetic factor for intestinal injury. Phosphatidylcholine (PC) is an essential component contributing to formation of a hydrophobic mucus layer. For evaluation of PC in the pathogenesis of inflammatory bowel disease, the concentration and composition of PC in the rectal mucus of patients with ulcerative colitis was determined. Electrospray ionization (ESI) tandem mass spectrometry (MS/MS) allows quantification of PC species and enables analysis of crude extracts.
