Chemical Information
FooDB NameL-Malic acid
DescriptionL-Malic acid, also known as malate or L-apple acid, 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. L-Malic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). L-Malic acid exists in all eukaryotes, ranging from yeast to humans. L-Malic acid, with regard to humans, has been found to be associated with several diseases such as alzheimer's disease, colorectal cancer, eosinophilic esophagitis, and missing teeth; L-malic acid has also been linked to the inborn metabolic disorder 2-ketoglutarate dehydrogenase complex deficiency.
