  <name>Hexacosanoic acid</name>
  <description>Hexacosanoic acid, also known as Hexacosanoic acid or Hexacosanoic acid, 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. Hexacosanoic acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Hexacosanoic acid exists in all eukaryotes, ranging from yeast to humans. In cattle, hexacosanoic acid is involved in the metabolic pathway called the Beta oxidation OF very long chain fatty acids pathway. Hexacosanoic acid is a potentially toxic compound.</description>
