例如：molar mass of CO2 = 44 g/mol； molar mass of NaCl = 58.5 g/mol 简单来说，只有 molar mass 的 unit 是 g/mol，而其他都是没有 unit 的 relative mass。以 H2SO4 为例（Pure H2SO4 is molecular）： Relative atomic mass of H = 1 Relative atomic mass of S = 32 Rela...

Sodium appetite is a motivational state involving homeostatic behavior, seeking the ingest of salty substances after sodium loss. There is a temporal dissociation between sodium depletion (SD) and the appearance of sodium appetite. However, the responsib

7. Objective:To establish a method to determine relative molecular mass and distribution of hydroxyethyl starch 130/0.4 and sodium chloride injection by size exclusion chromatography. 目的:建立凝胶色谱法由多角度激光光散射检测器和示差折光检测器联用测定羟乙基淀粉130/0.4氯化钠注射液相对分子质量及分布的方...
The products have been characterized by their proton NMR and mass spectra, and by single crystal X-ray diffraction investigations. (η 5-C 5H 5) 3Y · OC 4H 8[η 5-C 5H 5) 3 La · OC 4H 8] crystallizes in the monoclinic space group P2 1/ n[ P2 1/ n] with unit cell ...
The measured molecular weights in 0.05 M buffer agree with the mass of the intact (tetrameric) hemoglobin molecule. The apparent relative de-crease in molecular weight found in 2 M salt is too small to be considered significant in the case of carbon monoxyhemoglobin and is questionable for ...
4). Interestingly, SptF accepted all of them as substrates, except for 12. SptF thus installed a hydroxyl group at C1 of 10 to form 11 (Fig. 2a, d, Supplementary Figs. 43-48, and Supplementary Table 12). Notably, SptF oxidized all four terretonins to yield products with 2 mass ...
Much effort has been invested in the investigation of the structural basis of G protein-coupled receptors (GPCRs) activation. Inverse agonists, which can inhibit GPCRs with constitutive activity, are considered useful therapeutic agents, but the molecula
(TM1, 2, 6, 8, 11, and 12) located within − 40 < z < 20 Å were selected. The centre-of-mass of these Cα atoms in thexy-plane was used as the centre of the cylinder. The average distance in thexy-plane from the centre to these Cα atoms was used as the ...
