41. As such, target tissues are likely to be exposed to similar amounts of free estriol, estradiol, and estrone during pregnancy. 42. Estrone is the major estrogen in Premarin ( about 50 % ) and equilin is present as about 25 % of the total.43. "' Estropipate "'( salt of estrone sulfate and piperazine, and is hydrolyzed into estrone in the body. 44. "' Estropipate "'( salt of estrone sulfate and piperazine, and is hydrolyzed into estrone in the body. 45. Recent research shows that corticosterone inhibits the fat mobilizing effects of oleoyl-estrone in female rats that had their adrenal glands removed. 46. An "'estrogen ester "'is an ester of an estrogen, generally estradiol but also estrone or estriol. 47. It produces 8, 9-dehydroestradiol as an important active metabolite, analogously to conversion of estrone or estrone sulfate into estradiol. 48. It produces 8, 9-dehydroestradiol as an important active metabolite, analogously to conversion of estrone or estrone sulfate into estradiol. 49. It is also an important active metabolite of 8, 9-dehydroestrone, analogously to conversion of estrone or estrone sulfate into estradiol. 50. It is also an important active metabolite of 8, 9-dehydroestrone, analogously to conversion of estrone or estrone sulfate into estradiol.
