anhidrase

Anhidrase is a term derived from the Greek words "a-" meaning without, and "hydor" meaning water. It is used to describe substances or processes that do not involve water. In chemistry, an anhydrous compound is one that contains no water molecules. For example, sodium chloride (table salt) is often found in its anhydrous form, NaCl, rather than the hydrated form, NaCl·2H2O. In biology, the term is used to describe enzymes that do not require water to function, such as carbonic anhydrase, which catalyzes the conversion of carbon dioxide and water into bicarbonate and protons. Anhidrase can also refer to a condition characterized by excessive sweating, leading to dehydration and electrolyte imbalances. This condition can be caused by various factors, including certain medications, heat, or underlying medical conditions. Treatment typically involves addressing the underlying cause and managing symptoms with medications or lifestyle changes.
