Hydration

Information and facts about Nutrition.

In chemistry, hydration is the condition of being combined with water.

Hydration can create a hydrate from which water can be reextracted. When hydration occurs in a chemical reaction it is called a hydration reaction, in which water is permanently and chemically combined with a reactant in a way that it can no longer be reextracted.

An example of a hydration reaction is acid-catalyzed hydration of the carbon-carbon double bond in an alkene. H+ and OH- is added via Marknovnikov addition.

Hydration can cause hydrolysis.

An example of hydrate synthesis is hydration of a carbonyl group.

Hydration also is used to mean getting water into an organism, usually human. This is important when large amounts of body fluid are lost, such as by sweating.
