Class of chemical compounds
Lipoidal estradiol (LE2) is the variety of
hydrophobic and are found in highest concentrations in adipose tissue and other estrogen-sensitive tissues and in low but detectable concentrations in circulation, with none excreted in urine.[1][2] They have been referred to as the "endogenous counterparts of the synthetic esters of estrogens" like estradiol valerate and estradiol cypionate.[1][2]
Two of the estradiol esters that compose LE2, estradiol palmitate and estradiol stearate, have been developed and marketed for medical use as long-acting estrogens for use via depot intramuscular injection.[3][4]
Estradiol is esterified into LE2 by lecithin–cholesterol acyltransferase (LCAT).[5]
