Question

The Stork–Eschenmoser hypothesis was first identified from the biosynthesis of one of these compounds. Besides sterols and indoles, Salkowski’s test can be used to detect the presence of these compounds. The biosynthesis of these compounds is mediated by the TPS protein family, which uses GPP, FPP, or GGPP (15[1])as natural precursors. Those precursors form from the condensation of D·MAPP and I·P·P, produced either (15[2])by the MVA (15[1])or (-5[1])MEP (15[1])metabolic pathways. (15[1])Pyrolysis of (*) rubber yields (10[1])the most basic molecule used to make these compounds. The structural isomers of molecules that make up these compounds most commonly combine in the “head-to-tail” method, and the classification of these molecules is based on the C5 rule. In animals, a “tri” form of these molecules is the precursor to steroids. For 10 points, name these unsaturated hydrocarbons (-5[1])made of isoprene subunits. ■END■ (10[2]0[1])

ANSWER: terpenes [or terpenoids; accept isoprenoids, triterpene, or triterpenoid; prompt on isoprene until read by asking “what molecules are made of isoprene subunits?”]
