Correct spelling for the English word "estronol" is [ˈɛstɹənˌɒl], [ˈɛstɹənˌɒl], [ˈɛ_s_t_ɹ_ə_n_ˌɒ_l] (IPA phonetic alphabet).
Estronol is a term primarily used in the field of organic chemistry and medicine. It refers to a specific compound known as 3,17β-dihydroxyestra-1,3,5(10)-trien-17-ol, which is a type of estrogen hormone.
Estrogens are a group of steroid hormones that play a crucial role in various physiological processes, particularly in the development and maintenance of the female reproductive system. They are primarily produced in the ovaries and have diverse effects on the body. Estronol, specifically, is one of the main estrogenic compounds found in the urine of pregnant women, but it is also present in smaller quantities in non-pregnant individuals.
Chemically speaking, estronol is an oxygenated derivative of estrone, which is a natural form of estrogen produced by the ovaries. Estronol possesses two hydroxyl groups (-OH) attached to carbon positions 3 and 17β of the estrogenic backbone structure. These hydroxyl groups are believed to contribute to its estrogenic activity and interaction with estrogen receptors in the body.
In medicine, estronol is mostly regarded as a metabolite or an intermediate compound in the biosynthesis and metabolism of estrogens. Its precise role and significance in human physiology are still being studied and better understood. Furthermore, estronol also holds relevance in analytical chemistry as it is utilized as a reference standard during the identification and quantification of estrogenic compounds in biological samples.
