Common Name | 5alpha-Campestan-3-one |
---|
Description | 5alpha-Campestan-3-one, also known as 3-dehydro-campestanol or methylcholestanone, belongs to the class of organic compounds known as ergosterols and derivatives. These are steroids containing ergosta-5,7,22-trien-3beta-ol or a derivative thereof, which is based on the 3beta-hydroxylated ergostane skeleton. Thus, 5alpha-campestan-3-one is considered to be a sterol lipid molecule. 5alpha-Campestan-3-one is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 5alpha-Campestan-3-one is involved in the brassinosteroid biosynthesis pathway. 5alpha-Campestan-3-one is produced from campest-4-en-3-one by the action of DET2 (EC 1.3.99.-), a probable steroid reductase. 5alpha-Campestan-3-one is then converted into campestanol or 22alpha-hydroxy-5alpha-campestan-3-one. The conversion to 22alpha-hydroxy-5alpha-campestan-3-one is catalyzed by DWF4, a steroid 22-alpha-hydroxylase (EC 1.14.13.-). |
