- What is the absolute stereochemistry at carbons 1,2,3, and 5 ?The LD50 (“Lethal Dose, 50 %”) is a value used in toxicology which gives the amount of a substance required to kill 50 % of a test population. It is usually reported based on body weight. For racemic carvone LD50 is reported as 1640 mg/kg. 1. Would it consider carvone to be toxic to an average person? Explain. 2. Would it be expected this the LD50 value to be the same for each enantiomer? Explain at the molecular level in stereochemical terms.A difficult problem in the synthesis of PGF2α is the introduction of the OH group at C15 in the desired configuration. a.
