Input: Consider 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.

Output: Science

Input: Consider Input: This enzyme is degraded by the actions of victorin and the DNA-binding aspartic acid peptidase CND41, but is forced into a proteolysis-resistant state by the binding of its inhibitor CA1P. It is usually localized to to pyrenoids, and a lysine residue on it is carbamated by its namesake activase, which allows the positioning of a critical magnesium molecule. Phosphoglycolate is a side product of this enzyme, whose slow speed and penchant for leading to photorespiration is counteracted by PEP carboxylase in some organisms. FTP, name this enzyme, the most abundant protein on earth, that catalyzes a major step in the Calvin cycle by attaching a carbon dioxide molecule to Ribulose bisphosphate.

Output: Science

Input: Consider Input: As a youth he was sent to Rome where he was made either consul or king by Pope Leo IV and he was later responsible for reorganizing the fyrd. His defeat of Guthrun at the Battle of Eddington led to the Treaty of Widmore, which set up an area for autonomous Viking rule, the Danelaw. Although he is not William I, this king did create a Doom Book which was a code of law often named for him and which was prefaced by the Ten Commandments. This ruler also translated St. Augustine's Soliloquies and Boethius's Consolation of Philosophy into English and the Anglo-Saxon Chronicle began under his reign. For 10 points, identify this first King of the Anglo-Saxons, the only English king to be known as "the Great".
