Metabolite Identification
Common Name2-Hydroxy-3-methoxyestrone
Description2-Hydroxy-3-methoxyestrone is obtained after methylation of 2-Hydroxyestrone and is generally found in the urine as an excretion product. 2-hydroxyestrone is the result of the hydroxylation of estrone E1. The hydroxylation process helps to clear out E1 from the body. This is critical because higher lifetime exposure to estrogen has been found to increase cancer risks to the reproductive system, especially to the breast. However, 2-hydroxyestrone has a weak estrogenic activity and breast cancer risks are quite low in women with high urinary excretion of 2-hydroxyestrone. 2-Hydroxy-3-methoxyestrone levels in urine could be an indicator to help assess the risk factors for development of breast cancers.
