  <name>(±)-Isomenthol</name>
  <description>(±)-isomenthol is a member of the class of compounds known as menthane monoterpenoids. Menthane monoterpenoids 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 (±)-isomenthol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). (±)-isomenthol can be found in a number of food items such as cabbage, peppermint, sunflower, and white cabbage, which makes (±)-isomenthol a potential biomarker for the consumption of these food products. </description>
