Common NameHopan-22-ol
DescriptionHopan-22-ol, also known as 22-hopanol or 22-hydroxyhopane, belongs to the class of organic compounds known as hopanoids. These are terpenoids containing hopane skeleton(A'-Neogammacerane), a pentacyclic structure with four cyclohexane rings and one cyclopentane ring (and often, a side chain emerging from C30). Thus, hopan-22-ol is considered to be a hopanoid lipid molecule. Hopan-22-ol is found in Acetobacter pasteurianus, Adiantum capillus-veneris, Adiantum raddianum, Adiantum edgeworthii, Adiantum pedatum, Aleuritopteris kuhnii, Alsophila gigantea, Alsophila podophylla, Alsophila spinulosa, Asterella blumeana, Azolla nilotica, Cheilanthes marantae, Cheiropleuria bicuspis, Cyathea lepifera, Davallia mariesii, Dryopteris crassirhizoma, Fossombronia pusilla, Laurencia dendroidea, Lepisorus contortus, Lophosoria quadripinnata, Oleandra wallichii, Plagiochasma rupestre, Plagiogyria glauca, Pleopeltis polypodioides, Polypodium aureum and Polypodium formosanum. Hopan-22-ol was first documented in 2011 (PMID: 21261296). Hopan-22-ol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
