Progesterone is one of the progestan type of steroid hormones that is vital to pregnancy and it also is a precursor for some androgen and estrogen steroids.
Progesterone, a progestagen which prepares the lining of the uterus for implantation of an ovum, is biosynthesized from prognenolone by oxidation of the 3-hydroxy group into a 3-keto group and by the isomerization of the δ5 double bond into a δ4 double bond. This hormone is also essential to maintain pregnancy. Progresterone is the precursor chemical in the biosynthesis of corticoids and androgens.
