HumanCyc Reaction KEGG Pathway and corresponding reaction
cholesterol + an acyl-CoA = cholesterol ester + coenzyme A R0146 EC 2.3.1.26 in Bile acid biosynthesis pathway
O2 + NADPH + cholesterol = H2O + NADP± + 7α-hydroxycholesterol R01453 EC 1.14.13.- in biosynthesis of steroids
NADP+ + cholesterol = 7-dehydro-cholesterol + NADPH R01456 EC 1.3.1.21 in biosynthesis of steroids pathway
O2 + a reduced adrenal ferredoxin + cholesterol = H2O + an oxidized adrenal ferredoxin + 4-methylpentanal + pregnenolone R02724 EC 1.14.15.6 in C21-Steroid hormone metabolism
