Question
24. (3 points) Cholesterol is biosynthesized from squalene, a waxy substance first isolated from whale oil. The crucial first step is formation of so-called "squalene oxide". It then undergoes an enzyme catalyzed cyclizaiton reaction where the four rings of the steroid nucleus are formed simultaneously Although the same conditions are not used in the biosynthesis process, write a laboratory reagent in the box below that could turn squalene into "squalene oxide". Enzymatic Cyclization Ho Steroid nucleus Squalene oxide" Lanosterol CholesterdlExplanation / Answer
the conversion of squalene to squalene oxide by reacting with flavin hydroperoxide.
