[Variable Error]-Dopa (Levodopa) is an oral medication used to treat Parkinson's disease, the symptoms of which result from a lack of dopamine in the brain. [Variable Error]-Dopa relies on L-type, or leucine-preferring, transport proteins to cross the blood-brain barrier, and it is converted to dopamine in the brain by the enzyme aromatic-[Variable Error]-amino-acid decarboxylase. Properties of [Variable Error]-Dopa: - density: $$1.47\mathrm{g}/{\mathrm{cm}}^3$$ - melting point: $$278^{?}\mathrm{C}$$ - boiling point: decomposes - solubility in water: low solubility - solubility in lipids: low solubility - rotates plane-polarized light counterclockwise Classify each property based on whether it is or is not a property of [Variable Error]-Dopa's enantiomer, [Variable Error]-Dopa. rotates plane-polarized light clockwise good substrate for aromatic-L-amino-acid decarboxylase reduces symptoms of Parkinson's discase. Not a property of D-Dopa highly soluble in water density slightly less than that of L-Dopa Answer Bank
