Intracellular fluid is the cytosol of cytoplasm, a fluid located within the membrane of tissue cells. The proteins that are located within the cytosol act as intracellular receptors also play an important role in glycolysis and signal transduction pathways. These proteins form part of ribosomes, thus helping to enable protein synthesis. There are prokaryotes and eukaryotes. All chemical reactions in the case of prokyrates take place within cytosol whereas the cell organelles are contained by the cytosol collectively known as "cytoplasm" as in the case of eukaryotes. Cytosol has about 20% to 30% of protein and the details cytosol consists mostly of water, dissolved ions, large soluble water molecules such as protein as well as small molecules.
