  <description>D-Limonene, also known as L-limonen or dipentene, belongs to the class of organic compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. Thus, D-limonene is considered to be an isoprenoid lipid molecule. D-Limonene exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. D-Limonene exists in all living organisms, ranging from bacteria to humans.</description>
