[Q]: 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.

[Q]: Materials with this property can exhibit a noise arising from self-organized criticality known as the Barkhausen effect. The Ising model was originally formulated to study this phenomenon, in which regions become separated by Bloch walls and materials exhibiting this property are frequently subject to hysteretic effects. The anti variety of this property disappears above the Neel point, while this property itself disappears above the Curie point, where the material transitions to paramagnetism. FTP, identify this form of magnetism resulting from the spontaneous alignment of domains, which is present in metals such as nickel and iron.
[A]: Science
