Cytosol mostly consists of water, dissolvedions, small molecules, and large water-soluble molecules (such as protein). It contains about 20% to 30% protein.
Normal human cytosolic pH is (roughly) 7.0 (i.e. neutral), whereas the pH of the extracellular fluid is 7.4.
The texture of cytosol being described as granular can be attributed to the fact that in order to study the texture, an electron microsope must be used, which requires a process of dehydration prior to study.
