Metabolite Identification
Common NameHeptanoic acid
DescriptionHeptanoic acid, also known as enanthic acid or heptylic acid, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Heptanoic acid exists as a liquid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Heptanoic acid exists in all eukaryotes, ranging from yeast to humans. Heptanoic acid is a potentially toxic compound.
