Chemical Information
FooDB NamePentacosanoic acid
DescriptionPentacosanoic acid, also known as pentacosanoate or hyenate, 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. Pentacosanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Pentacosanoic acid is a potentially toxic compound.
