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 ′).

Phosphomonoesters (or phosphoric esters) are chemical compounds containing one ester bond and a phosphate group. In biology, phosphomonoesters are needed as the building blocks for the synthesis of Phospholipid cellular membranes, especially those found on neurons. [1] Enzymes which cleave these bonds are known as phosphomonoesterases, or ...
Molecular structure of 1-monoacylglycerol Molecular structure of 2-monoacylglycerol. Monoglycerides (also: acylglycerols or monoacylglycerols) are a class of glycerides which are composed of a molecule of glycerol linked to a fatty acid via an ester bond. [1]
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 ...
Specifically, it is the phosphodiester bonds that link the 3' carbon atom of one sugar molecule and the 5' carbon atom of another (hence the name 3', 5' phosphodiester linkage used with reference to this kind of bond in DNA and RNA chains). [3] The involved saccharide groups are deoxyribose in DNA and ribose in RNA.
Hydrolases can be further classified into several subclasses, based upon the bonds they act upon: EC 3.1: ester bonds (esterases: nucleases, phosphodiesterases, lipase, phosphatase) EC 3.2: sugars (DNA glycosylases, glycoside hydrolase) EC 3.3: ether bonds; EC 3.4: peptide bonds (Proteases/peptidases) EC 3.5: carbon-nitrogen bonds, other than ...
Coenzyme A (CoA, SHCoA, CoASH) is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle.All genomes sequenced to date encode enzymes that use coenzyme A as a substrate, and around 4% of cellular enzymes use it (or a thioester) as a substrate.
