Ex Input:
The enzyme LCAT catalyzes the formation of an ester from this compound. Intermediates in the synthesis of this compound include squalene [SKWAY-leen] and mevalonate [muh-VAL-uh-nate], the latter of which is produced by HMG-CoA reductase. Vitamin D is formed from the 7-dehydro form of this compound, which reduces membrane fluidity. This compound, which is transported to the liver by high-density lipoprotein, is linked to heart disease. For 10 points, name this compound whose amount in the blood is lowered by statins such as Crestor and Lipitor.

Ex Output:
Science

Ex Input:
Instead of employing the Debye-Hull-Scherrer powder method, its namesakes relied on an array of atomic planes. Its namesakes built a vacuum apparatus and employed a hot filament, an accelerating electrode, and an arc-mounted Faraday box. A leak in the vacuum led its namesakes to heat the target, resulting in crystallized nickel, which gave startling results. A plot of collector current against beam energy was explained by constructive interference, and the results in general could be derived by combining Bragg's equation with the de Broglie wavelength for electrons. FTP name this experiment named for two physicists, which proved that electrons diffract.

Ex Input:
This man caused the Ottoman Interregnum as a result of one battle, and his lands were inherited by Shah Rokh. He supposedly kept a prisoner in an iron cage, destroyed a rival completely at the Battle of Terek River.
