An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
In organic chemistry and biochemistry esters are the functional group (R'-COOR") consisting of an organic radical united with the residue of any oxygen acid, either organic or inorganic. An ester is a product of the reaction of an acid (usually organic) and an alcohol (the hydrogen of the acid R-COOH is replaced by an alkyl group R").
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

Beclometasone dipropionate, an example of a widely used corticosteroid ester. Note the propionate groups at the C17α and C21α positions (top right corner). This is a list of corticosteroid esters, including esters of steroidal glucocorticoids and mineralocorticoids. [1] [2] [3]
This is a list of estrogen esters, or ester prodrugs of estrogens. It includes esters, as well as ethers , of steroidal estrogens like estradiol , estrone , and estriol and of nonsteroidal estrogens like the stilbestrols diethylstilbestrol and hexestrol .
This is a complete list of estrogens and formulations that are approved by the FDA Tooltip Food and Drug Administration and available in the United States. Estrogens are used as hormonal contraceptives , in hormone replacement therapy , and in the treatment of gynecological disorders .
This is a list of steroidal estrogens or derivatives of estradiol, estrone, and estriol. Most esters of these estrogens are not included in this list; for esters, see here instead. Estradiol derivatives
This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide, water and oxygen were necessary for the growth of life.
