What is the difference between estriol and estrone?

Estrone is an estrogen, specifically an agonist of the estrogen receptors ERα and ERβ. It is a far less potent estrogen than is estradiol, and as such, is a relatively weak estrogen. Given by subcutaneous injection in mice, estradiol is about 10-fold more potent than estrone and about 100-fold more potent than estriol.

What is the function of estrone?

As an estrogen, estrone is responsible for female sexual development and function. Because it is less powerful than the other estrogens, estrone can sometimes serve as a repository for estrogens, and the body can convert it to estrogen when needed.
