In enzymology a cholestenol Delta-isomerase (EC 5.3.3.5) is an enzyme that catalyzes the chemical reaction5alpha-cholest-7-en-3beta-ol 5alpha-cholest-8-en-3beta-olHence this enzyme has one substrate 5alpha-cholest-7-en-3beta-ol and one product 5alpha-cholest-8-en-3beta-ol.This enzyme belongs to the family of isomerases specifically those intramolecular oxidoreductases transposing C=C bonds. The systematic name of this enzyme class is Delta7-cholestenol Delta7-Delta8-isomerase.
