| What is it? | |
|
A group of structurally related
hormones, based on the
cholesterol molecule. They control sex and growth characteristics, are
highly lipophilic (having an affinity for fat), and are unique in that
their
receptors are in the nucleus,
rather than on the
plasma membrane.
Also see hormone. Examples: testosterone, estrogen. |
