question:
Melamine resin is formed by dehydration of this compound, while barbiturates can also be formed by addition of this compound to malonic acid. Other uses of this compound include separation of racemic mixtures. Originally produced by a reaction between silver cyanate with ammonium chloride, it is now made in indusrial quantities by heating carbon dioxide with ammonia. When arginine is split, it forms an ornithine molecule and a molecule of this; the principal end product of mammalian nitrogen metabolism. First isolated by H.M.

answer:
Science


question:
This compound promotes the dephosphorylation and activation of enzyme HMG-CoA to favor cholesterol synthesis and a phenylalanine for leucine substitution at residue B25 results in its "Chicago" variety. Its biosynthesis involves an excision of the C-peptide, and the compound functions by binding to tyrosine kinase receptors on cell surfaces. Sanger's improvement upon the methods of Edman degradation involved its sequencing, and its production occurs primarily in beta cells on the islets of langerhans. For ten points, name this pancreatic counterpart of glucagon used to regulate blood sugar, deficiencies of which are found in sufferers of diabetes.  
answer:
Science


question:
One work with this name was commissioned by the National Music Camp in 1974, and the second of its three movements is an Adagio subtitled The Untold Want. The composer of that work discussed composing it at age 80 in the same interview with David Williams in which he noted that it was Sibelius rather than Nielsen that had influenced his Nordic Symphony. Another work by this title is a setting of the same text as the first movement of Roy Harriss Symphony for Voices. Both its baritone and soprano soloists are featured in its fourth and final movement, a setting of the poem Passage to India known as The Explorers, which is preceded by Scherzo: The Waves. For 10 points, identify this title shared by Howard Hansons seventh and Ralph Vaughan Williams first symphonies, settings of such poems from Walt Whitmans Leaves of Grass as Joy, Shipmate, Joy! and On the Beach at Night Alone.
