Unsaturation of serine lipids modulating the interaction of a cystoporone with models of the external leaflet of tumorigenic cell membranes
Chem Phys Lipids. 2023 Nov 30:105363. doi: 10.1016/j.chemphyslip.2023.105363. Online ahead of print.ABSTRACTCystoporone-B was isolated from fungi and incorporated in models of tumorigenic cell membranes using palmitoyloleoylglycerophosphoserine (POPS) and dipalmitoyl glycerophosphoserine (DPPS) lipids. While for DPPS, the compound condensed the monolayer and decreased the surface compressional modulus, it expanded and kept the compressional modulus for POPS. Hysteresis for compression-expansion cycles was more sensitive for POPS than for DPPS, while a high degree of destabilization was observed for POPS. As observed with i...

Monitoring galactolipid digestion and simultaneous changes in lipid-bile salt micellar organization by real-time NMR spectroscopy
Chem Phys Lipids. 2023 Nov 21;258:105361. doi: 10.1016/j.chemphyslip.2023.105361. Online ahead of print.ABSTRACTThe use of Nuclear Magnetic Resonance spectroscopy for studying lipid digestion in vitro most often consists of quantifying lipolysis products after they have been extracted from the reaction medium using organic solvents. However, the current sensitivity level of NMR spectrometers makes possible to avoid the extraction step and continuously quantify the lipids directly in the reaction medium. We used real-time 1H NMR spectroscopy and guinea pig pancreatic lipase-related protein 2 (GPLRP2) as biocatalyst to monit...
