| There are three major hormones estradiol, estrone, and estriol among the estrogens, and estradiol is the predominant one. |
| After menopause estradiol levels drop more than estrone so that now estrone is the predominant estrogen. |
| In one study, coral homogenates metabolized estradiol into estrone and testosterone into androstenedione and androstanedione. |
| There were increases in blood levels of the estrogens, estradiol and estrone, and a reduction of the protective HDL cholesterol. |
| Examples include estradiol, estrone, estriol, progesterone and testosterone. |
| After estrone hydroxylation, the various poly-hydroxy derivatives are conjugated with glucuronate or sulfate, or methylation occurs prior to excretion in urine. |
