Round 7: Tossup 1

The glutathione-ascorbate cycle rids the body of this molecule and its derivatives. This molecule is released in the conversion of glycolate (-5[1])to glyoxylate, the latter of which names an analog of the TCA in the plant version of a certain organelle. The metalloenzyme superoxide dismutase releases oxygen and this molecule as a byproduct. Derivatives of this molecule name a structure that performs very (*) long-chain fatty acid oxidation. Homolytic cleavage of this molecule produces a pair of highly damaging hydroxyl radicals. (10[1])This ROS is decomposed into water and oxygen gas by the enzyme catalase. For 10 points, name this molecule with formula H2O2. (10[1])■END■ (10[1])

ANSWER: hydrogen peroxide [accept H2O2 before read; prompt on peroxisome; anti-prompt on peroxides by asking “what is the simplest molecule of that type?”]
