Question
These molecules are industrially fermented by Corynebacterium glutamicum. The herbicide Roundup blocks the synthesis of these molecules via the shikimate (“SHICK-uh-mate”) pathway. Tryptone is added to LB to feed bacteria these molecules. Biosynthesis of one of these molecules is impaired in the Salmonella used for the Ames test and in the yeast auxotroph “His (“hiss”) minus.” Simulating a primordial atmosphere and (*) lightning produced five of these molecules abiotically in the Urey-Miller experiment. The central carbon of these molecules is bonded to a -COOH (“C O O H”) group, an -NH2 (“N H two”) group, and an R group. Humans synthesize half the canonical set of these molecules, but the other ten are essential. For 10 points, name these building blocks of proteins. ■END■
ANSWER: amino acids [or AAs; accept canonical amino acids or essential amino acids; prompt on residues; prompt on acids; prompt on peptides or proteins until “Ames” is read and reject afterwards]
