anhydrase

anhydrase

[an-hi´drās]

an enzyme that catalyzes the removal of water from a compound.

carbonic anhydrase an enzyme that catalyzes the decomposition of carbonic acid into carbon dioxide and water, facilitating transfer of carbon dioxide from tissues to blood and from blood to alveolar air.

an·hy·drase

(an-hī'drās),

An enzyme that catalyzes the removal of water from a compound; most such enzymes are now known as hydrases, hydro-lyases, or dehydratases.

anhydrase

[anhī′drās]

Etymology: Gk, a, not + hydor, water

an enzyme that catalyzes the elimination of water molecules from certain compounds, as carbonic anhydrase dehydrates carbonic acid, thereby controlling the amount of carbon dioxide in the blood and lungs.

an·hy·drase

(an-hī'drās)

An enzyme that catalyzes the removal of water from a compound; most such enzymes are now known as hydrases, hydrolyases, or dehydratases.

anhydrase

an enzyme that catalyzes the removal of water from a compound.

carbonic anhydrase

a zinc-containing enzyme that catalyzes the decomposition of carbonic acid into carbon dioxide and water, facilitating transfer of carbon dioxide from tissues to blood and from blood to alveolar air. See also carbonic anhydrase.
