By Sally Robertson, BSc. The term demyelination refers to loss of the myelin sheath that surrounds and protects axons in the central nervous system. Demyelination occurs as the result of diseases that damage the myelin sheath or the cells that form it. Diseases that are characterized by this loss of myelin are referred to as demyelinating diseases. The myelin sheath covers and insulates axons, aiding the conduction of electrical signals between nerves.
For the removal of water from solvents and reagents, see desiccation. In chemistry and the biological sciences, a dehydration reaction is usually defined as a chemical reaction that involves the loss of a water molecule from the reacting molecule. Dehydration reactions are a subset of condensation reactions.ome dehydration reactions can be mechanistically complex, for instance the reaction of a sugar (sucrose) with concentrated sulfuric acid: to form carbon as a graphitic foam involves formation of carbon-carbon bonds.
