In enzymology a cholesterol 25-hydroxylase (EC 1.14.99.38) is an enzyme that catalyzes the chemical reactioncholesterol + AH2 + O2 25-hydroxycholesterol + A + H2OThe 3 substrates of this enzyme are cholesterol an electron acceptor AH2 and O2 whereas its 3 products are 25-hydroxycholesterol (25HC) the reduction product A and H2O.This enzyme belongs to the family of oxidoreductases specifically those acting on paired donors with O2 as oxidant and incorporation or reduction of oxygen.
