In enzymology, a 3-hydroxypalmitoyl-[acyl-carrier-protein] dehydratase is an enzyme that catalyzes the chemical reaction -3-hydroxypalmitoyl-[acyl-carrier-protein] ⇌ {\displaystyle \rightleftharpoons } hexadec-2-enoyl-[acyl-carrier-protein] + H2OHence, this enzyme has one substrate, [[-3-hydroxypalmitoyl-[acyl-carrier-protein]]], and two products, [[hexadec-2-enoyl-[acyl-carrier-protein]]] and H2O.
