Cholesterol 24-hydroxylase, also commonly known as cholesterol 24S-hydroxylase, cholesterol 24-monooxygenase, CYP46, or CYP46A1, is an enzyme that catalyzes the conversion of cholesterol to 24S-hydroxycholesterol. It is responsible for the majority of cholesterol turnover in the human central nervous system. The systematic name of this enzyme class is cholesterol,NADPH:oxygen oxidoreductase (24-hydroxylating).

25-hydroxycholesterol 7-alpha-hydroxylase also known as oxysterol and steroid 7-alpha-hydroxylase is an enzyme that in humans is encoded by the CYP7B1 gene. This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids.
Methylsterol monooxygenase (EC 1.14.13.72, methylsterol hydroxylase, 4-methylsterol oxidase, 4,4-dimethyl-5alpha-cholest-7-en-3beta-ol,hydrogen-donor:oxygen oxidoreductase (hydroxylating)) is an enzyme with systematic name 4,4-dimethyl-5alpha-cholest-7-en-3beta-ol,NAD(P)H:oxygen oxidoreductase (hydroxylating). This enzyme catalyses the following chemical reaction
Taurochenodeoxycholate 6alpha-hydroxylase (EC 1.14.13.97, CYP3A4, CYP4A21, taurochenodeoxycholate 6alpha-monooxygenase) is an enzyme with systematic name taurochenodeoxycholate,NADPH:oxygen oxidoreductase (6alpha-hydroxylating). This enzyme catalyses the following chemical reaction
Abieta-7,13-dien-18-ol hydroxylase (EC 1.14.13.109, CYP720B1, PTAO) is an enzyme with systematic name abieta-7,13-dien-18-ol,NADPH:oxygen oxidoreductase (18-hydroxylating). This enzyme catalyses the following chemical reaction
Tryptophan N-monooxygenase (EC 1.14.13.125, tryptophan N-hydroxylase, CYP79B1, CYP79B2, CYP79B3) is an enzyme with systematic name L-tryptophan,NADPH:oxygen oxidoreductase (N-hydroxylating). This enzyme catalyses the following chemical reaction

24S-Hydroxycholesterol (24S-HC), also known as cholest-5-ene-3,24-diol or cerebrosterol, is an endogenous oxysterol produced by neurons in the brain to maintain cholesterol homeostasis. It was discovered in 1953 by Alberto Ercoli, S. Di Frisco, and Pietro de Ruggieri, who first isolated the molecule in the horse brain and then demonstrated its presence in the human brain.
