产品介绍
雌二醇是体内重点由卵巢成熟滤泡分泌的一种自然雌激素，能增进和调节妇性器官及副性征的正常发育。 雌二醇estradiol-C18H24O2是一种甾体雌激素。有α，β两种类型，α型生理作用强。温特斯坦纳等（Wintersteiner et al．1935）曾从妊娠马尿中提取出来，此外也可从妊妇尿、人胎盘、猪卵巢等中获得。雄马的精巢或尿中也存在。因为它有很强的性激素作用，所以认为它或它的酯实际上是卵巢分泌的最重要的性激素。
背景资料
Estradiol (known as alpha Estradiol or 17 alpha Estradiol) is a biologically active estrogen in human breast cancer cells in tissue culture.17-estradiol and its selective receptor, ER-X, are not part of a classical hormone/receptor endocrine system but of a system with important autocrine/paracrine functions in the developing and adult brain. 17-Estradiol may have enormous implications for hormone replacement strategies at the menopause and in the treatment of such neurodegenerative disorders as Alzheimer’s disease and ischemic stroke.
