Metabolite Identification
Common NameThymol
DescriptionThymol, also known as 3-p-cymenol or apiguard, belongs to the class of organic compounds known as aromatic monoterpenoids. These are monoterpenoids containing at least one aromatic ring. Thus, thymol is considered to be an isoprenoid lipid molecule. Thymol exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Thymol exists in all eukaryotes, ranging from yeast to humans.
