Metabolite Identification
Common NameArachidonic acid
DescriptionArachidonic acid, also known as arachidonate or AA, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Arachidonic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Arachidonic acid exists in all living organisms, ranging from bacteria to humans. Arachidonic acid has been found to be associated with several diseases known as colorectal cancer, hypertension, bladder infections, and gestational diabetes; also arachidonic acid has been linked to the inborn metabolic disorders including isovaleric acidemia.
