Excerpt: The nucleosol is a fluid suspension of a colloidal solid in a liquid inside the nucleus of a cell. The structural and functional unit of all known living organisms is the cell. Eukaryotic cells of which humans are composed contain membrane-bound compartments. The most important among these is the cell nucleus. It is the "control center" for each cell that has at least one. Separating the nucleus from the cellular cytoplasm is the double-membraned structure of the nuclear envelope. Inside the nuclear membrane, including attached to the inner layer of this membrane, are a variety of substances serving special purposes. Depending on conditions, for a time, some of these are within the nucleosol, some compose the nucleohyaloplasm, and still others compose the nucleoplasm. These substances and the special conditions present, even if temporary, in water, the liquid of the nucleosol, are components of the nucleosol. The nucleus cannot succeed in its efforts to control the cell without the special properties of the nucleosol. Generally, in chemistry a fluid suspension of a colloidal solid in a liquid is referred to as a sol. Whereas, a solution is a liquid mixture of a minor component (the solute) distributed uniformly within the major component (the solvent). In the nucleosol the liquid is water and the solvent is also water. Using the water (data page) and the atomic radii of the elements (data page), a water molecule is approximately 120 x 187 pm in maximum diameters (average 154 pm). For its small size a water molecu...
