The conversion of ethanol to ethylene is a fundamental example: [3] [4] CH 3 CH 2 OH → H 2 C=CH 2 + H 2 O. The reaction is accelerated by acid catalysts such as sulfuric acid and certain zeolites. These reactions often proceed via carbocation intermediates as shown for the dehydration of cyclohexanol. [5] Some alcohols are prone to dehydration.
Chronic dehydration, such as from physically demanding jobs or decreased thirst, can lead to chronic kidney disease. [51] Elderly people with dehydration are at higher risk of confusion, urinary tract infections, falls, and even delayed wound healing. [52] In children with mild to moderate dehydration, oral hydration is adequate for a full ...
The reaction may otherwise involve the functional groups of the molecule, and is a versatile class of reactions that can occur in acidic or basic conditions or in the presence of a catalyst. This class of reactions is a vital part of life as it is essential to the formation of peptide bonds between amino acids and to the biosynthesis of fatty ...

The Dangers of Dehydration-Related Blood Pressure Fluctuations “Dehydration-related changes in blood pressure, in particular, can be harmful because they can have an impact on the heart and the ...
The first are dehydration synthesis reactions; these involve the joining of smaller molecules together to form larger, more complex molecules. These include the formation of carbohydrates, proteins, lipids and nucleic acids. The second are reduction reactions, in which hydrogens and electrons are added to a molecule.
Dehydration has more extreme symptoms. Gervacio says this can include rapid heartbeat, low blood pressure, dry skin, little or no urine, very dark-colored urine, weakness and being extremely thirsty.
For example, water intoxication (which results in hyponatremia), the process of consuming too much water too quickly, can be fatal. Deficits to body water result in volume contraction and dehydration. Diarrhea is a threat to both body water volume and electrolyte levels, which is why diseases that cause diarrhea are great threats to fluid balance.
