Common Name(20R)-Protopanaxdiol
DescriptionProtopanaxadiol belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Thus, protopanaxadiol is considered to be an isoprenoid lipid molecule. (20R)-Protopanaxdiol is found in Panax ginseng. (20R)-Protopanaxdiol was first documented in 2013 (PMID: 23281928). Protopanaxadiol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 23391424).
