Description4α-carboxy-4β-methyl-5α-cholesta-8,24-dien-3β-ol, also known as 4alpha-carboxy-4beta-methyl-zymosterol, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Thus, 4α-carboxy-4β-methyl-5α-cholesta-8,24-dien-3β-ol is considered to be a sterol lipid molecule. 4α-carboxy-4β-methyl-5α-cholesta-8,24-dien-3β-ol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
