NameLanosterin
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionLanosterin, also known as botalan base 138 or lanosterol, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Thus, lanosterin is considered to be a sterol lipid molecule. Lanosterin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
