According to some authors, organyl derivatives of acidic hydrogen of other acids are esters as well (e.g. amides), but not according to the IUPAC. [ 1 ] An example of an ester formation is the substitution reaction between a carboxylic acid ( R−C(=O)−OH ) and an alcohol (R'OH), forming an ester ( R−C(=O)−O−R' ), where R and R′ are ...
According to some authors, those compounds are esters as well, especially when the first carbon atom of the organyl group replacing acidic hydrogen, is replaced by another atom from the group 14 elements (Si, Ge, Sn, Pb); for example, according to them, trimethylstannyl acetate (or trimethyltin acetate) CH 3 COOSn(CH 3) 3 is a trimethylstannyl ...
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").
Triglycerides are then commonly named as esters of those acids, as in glyceryl 1,2-dioleate 3-palmitate, the name for a brood pheromone of the honey bee. [8] Where the fatty acid residues in a triglyceride are all the same, names like olein (for glyceryl trioleate) and palmitin (for glyceryl tripalmitate) are common. [citation needed]
They are the esters of nitric acid and alcohols. A well-known example is nitroglycerin, which is not a nitro compound, despite its name. Pentaerythritol tetranitrate is a commercially important explosive that contains four nitrate ester groups.
The most commonly used alcohol is methanol, producing fatty acid methyl esters (FAME). When ethanol is used fatty acid ethyl esters (FAEE) are created. Other alcohols used for the production of biodiesel include butanol and isopropanol. Fatty acid ethyl esters are biomarkers for the consumption of ethanol (alcoholic beverages). [1] [2] [3]
Acetyl-CoA, the most common derivative, serves as an acyl donor in many biosynthetic transformations. Such acyl compounds are thioesters. Names of acyl groups of amino acids are formed by replacing the -ine suffix with -yl. For example, the acyl group of glycine is glycyl, and of lysine is lysyl.
The suffix-oate is the IUPAC nomenclature used in organic chemistry to form names of compounds formed with ester. They are of two types: They are of two types: Formed by replacing the hydrogen atom in the –COOH by some other radical , usually an alkyl or aryl radical forming an ester .
