Estrogens
Estrogens are steroids. They
are primarily responsible for the conversion of girls into sexually-mature women.
estrogen A female sex hormone that performs many important functions in reproduction.

Estrogen and testosterone are steroid hormones, and are most likely to bind to:

Estrogen and progesterone stimulate the development of the endometrium and preparation of the uterine inner lining for implantation of a zygote. If pregnancy does not occur, the drop in FSH and LH cause the corpus luteum to disintegrate.
Estrogen increases the risk of endometrial cancer but progesterone reduces the risk.

Estrogen replacement therapy has been used since the condition was described in 1938 to promote development of secondary sexual characteristics. Estrogens are also important for maintaining good tissue and bone integrity.[9] ...

estrone An animal steroid found in some plants in low concentration.

The reason the animals act this way is due to their hormonal cycles, which cause some to act as males when levels of estrogen are low, and others to take the role of female when estrogen levels are high.
(vertebrates) one of usually two organs that produce ova and secrete estrogen and progesterone.
Scientists there also have developed fluorine-18 fluoroestradiol that targets estrogen receptors on breast tumors.
Examples include insulin, estrogen, and testosterone.
Intermediate filament Part of the cytoskeleton that provides strength. Some intermediate filaments form nails, hair, and the outer layer of skin. Others are found in nerves or other organs.
Sequences of response elements are required for the functions of the transcription factors. Examples: Estrogen Response Element (ERE), Glucocorticoid Response Element (GRE), Progesterone Response Element (PRE).
follicles
Microscopic structures in the ovary that contain developing ova and secrete estrogens.
foot
The molluscian organ of locomotion.
Other sterols you are familiar with are the hormones, testosterone, estrogen, progesterone and cortisone. Because these hormones are fat soluble, they can enter the cell easily and do not require special receptors as the protein hormones do.
