What is Estrone?

Estrone, also known as E1 or oestrone, is a steroid like estriol and estradiol, belonging to the class of estrogens.  Estrone is one of the major hormones found in the bodies of postmenopausal women.  The estrogens are involved in the development of female sex organs and secondary sex characteristics. Before the ovum is fertilized the main action of the estrogens is on the growth and function of the reproductive tract in order to prepare it for the fertilized ovum. During the follicular phase of the menstrual cycle the Estrone level shows a slight increase.

Applications of Estrone

- as medium supplement for hormone based degranulation studies of natural killer cells.

- as an endocrine disrupting compound for screening bacterial biosensor in toxic water.

- as medium component for monitoring fatty acid synthase (FASN) activity in breast adenocarcinoma cell lines

How does Estrone work?

As an estrogen, Estrone is responsible for female sexual development and function. Because it is less powerful than the other estrogens, Estrone can sometimes serve as a repository for estrogens, and the body can convert it to estrogen when needed.

Symptoms of high Estrone

Estrone is very important in the female body as all the forms of estrogen are. It is important that estrone is balanced with the estradiol and estriol otherwise, too high estrone can cause unwanted symptoms.

- Weight gain, especially in the waistline and abdomen

- Moodiness: emotional with more of a tendency toward feeling weepy and easily irritated

- Cravings: munchies for processed carbohydrates such as sugars

- Fatigue: sleepy in the day and hard to wake up in the morning

- Heavy periods: periods are longer and heavier with more clotting

- Midcycle spotting can happen when estrone is high or not balanced with estriol and estradiol

- Irregular bleeding can occur is the estrone is too high with hormone replacement
