Chemical Information
FooDB NameEstriol
DescriptionEstriol, also known as estriel or 16a,17b-estriol, belongs to the class of organic compounds known as estrogens and derivatives. These are steroids with a structure containing a 3-hydroxylated estrane. Thus, estriol is considered to be a steroid lipid molecule. Estriol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Estriol is a potentially toxic compound.
