  <name>Dodecanoic acid</name>
  <description>Dodecanoic acid, also known as dodecanoate or potassium laurate, 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. Dodecanoic acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Dodecanoic acid exists in all living species, ranging from bacteria to humans. Dodecanoic acid participates in a number of enzymatic reactions, within cattle. In particular, Dodecanoic acid and coenzyme A can be converted into lauroyl-CoA and L-carnitine; which is catalyzed by the enzyme carnitine O-palmitoyltransferase 2, mitochondrial. In addition, Dodecanoic acid can be converted into dodecanoic acid; which is catalyzed by the enzyme peroxisomal membrane protein 11C. In cattle, dodecanoic acid is involved in the metabolic pathway called the Beta oxidation OF very long chain fatty acids pathway. Dodecanoic acid is a potentially toxic compound.</description>
