Common NameTricosanoic acid
DescriptionTricosanoic acid, also known as N-tricosanoate or 22FA, belongs to the class of organic compounds known as very long-chain fatty acids. These are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Tricosanoic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Tricosanoic acid is a potentially toxic compound.
