We recently developed a method for estimating protein dynamics in vivo with heavy water ( 2 H 2 O) using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI–TOF MS) [16], and we confirmed that 2 H labeling of many hepatic free amino acids rapidly equilibrated with body water. Although this is a reliable method, it required modest sample purification...
Adsorption of light and heavy water (H2O and D2O) on porous hypercross-linked polystyrene MN-272 was studied by gas chromatography. For the estimation of the properties of this polymer surface, n-alkanes (C6—C9), C66, and polar compounds (CHCl3, MeNO2, MeCN, Me2CO, EtCOOCH3, Et2O) were used as test adsorbates. The contributions of energies of dispersion and specific (donor-acceptor) intermolecular...
