Common NameTropic acid
DescriptionTropate, also known as (+-)-tropic acid or (+-)-tropate, belongs to the class of organic compounds known as beta hydroxy acids and derivatives. Beta hydroxy acids and derivatives are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom. Tropate is an extremely weak basic (essentially neutral) compound (based on its pKa). Tropate exists in all eukaryotes, ranging from yeast to humans. A 3-hydroxy monocarboxylic acid that is propionic acid in which one of the hydrogens at position 2 is substituted by a phenyl group, and one of the methyl hydrogens is substituted by a hydroxy group.
