Packet 1: Bonus 20
Deficiency in the ALA Synthase enzyme that catalyzes the synthesis of these molecules results in X-linked sideroblastic anemia. For 10 points each,
[10h] Name these molecules consisting of four pyrrole rings that serve as a tetradentate ligand for many metals.
ANSWER: porphyrins [prompt on but DO NOT REVEAL chlorophyll or heme with “What general class of molecules does it belong to?”]
[10e] A porphyrin ring surrounds the central iron atom in this protein that carries oxygen in red blood cells.
ANSWER: hemoglobin
[10m] The Rothenmund reaction, a clever way to synthesize porphyrins, reacts pyrrole with this functional group. These terminal carbonyls produce a silver mirror in Tollens’ test.
ANSWER: aldehyde [accept aldoses]
