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).
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 ′).

It also contains an ester functional group (in red), and an acetyl functional group (encircled with dark green). Other divisions can be made. Other divisions can be made. In organic chemistry , a moiety ( / ˈ m ɔɪ ə t i / MOY -ə-tee ) is a part of a molecule [ 1 ] [ 2 ] that is given a name because it is identified as a part of other ...
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"). Subcategories This category has the following 49 subcategories, out of 49 total.
A general acyl group (blue) in a ketone (top left), as an acylium cation (top centre), as an acyl radical (top right), an aldehyde (bottom left), ester (bottom centre) or amide (bottom right). ( R 1 , R 2 and R 3 stands for organyl substituent or hydrogen in the case of R 1 )
Polytestosterone phloretin phosphate (PTPP) is an androgen and anabolic steroid as well as androgen ester which was never marketed. [1] It is an ester of testosterone with phosphoric acid that is in the form of a polymer and is coupled with phloretin. [1] Like other androgen esters, PTPP acts as a long-lasting prodrug of testosterone in the ...
Cholesterol oleate, a member of the cholesteryl ester family. Cholesteryl esters are a type of dietary lipid and are ester derivatives of cholesterol. The ester bond is formed between the carboxylate group of a fatty acid and the hydroxyl group of cholesterol. Cholesteryl esters have a lower solubility in water due to their increased ...
In organic chemistry, an active ester is an ester functional group that is highly susceptible toward nucleophilic attack. Activation can be imparted by modifications of the acyl or the alkoxy components of a normal ester, say ethyl acetate. Typical modifications call for electronegative substituents.
