Hyaloplasma: fluid present inside cells
Definition - what it is
Also known as cytosol, hyaloplasma is a fluid present within the cells of living things. It is the soluble part of the cytoplasm.
- In the peripheral areas of the cytoplasm, it presents as a colloidal matter (viscous gel species). In the inner part (endoplasma), hyaloplasma has a more fluid consistency;
- It is composed of water, mineral salts, proteins, sugars and free amino acids;
- Corresponds to about 50% of the cell volume.
Hyaloplasma (cytosol) is responsible for much of the chemical reactions of cellular metabolism. It is in hyaloplasma that glycolysis and biosynthesis of sugars occurs.
- It is in hyaloplasma that occurs, through chemical reactions, molecules that form cellular structures.
- It is in hyaloplasma that storage of reserve substances used by cells occurs.
