Packet 11: Tossup 12

These compounds are produced by reacting aldehydes with cyanide in the presence of ammonia in the Strecker synthesis. During cooking, these compounds react with reducing sugars to create melanoidins in the Maillard (“my-ARD”) reaction. Several of these compounds were produced by applying an electric arc to a mixture meant to simulate Earth’s early (*) atmosphere in (10[1])the Miller–Urey experiment. These compounds are classified by the properties of their side chains; for example, asparagine is polar. There are nine “essential” examples of these compounds only obtainable through one’s diet. For 10 points, name these building blocks of proteins. ■END■
