WebImportant in the transport of respiration gases is the relative diffusion rate of oxygen and carbon dioxide in the plasma of the human body. Carbon dioxide has 22 times the solubility, but is more massive (44 amu compared to 32 for oxygen). According to Graham's law, the relative rate of diffusion is given by WebThe differences in the rates between the two MD models may be largely attributed to the hydrogen to oxygen charge difference, where the greater charge difference in the OPLS3 model leads to a greater strength and frequency of “hydrogen bonding” and a slower rate of translational and rotational diffusion.
