The word "ester" is correct and usable in written English.
It can be used as a noun to refer to a type of organic compound or as an adjective to describe something that is esterified. Example sentence: The ester bonds in the molecule were broken during the chemical reaction.
This forms in pouches next to their anuses and they smear it onto plants for other hyenas to sniff and draw conclusions about the depositor.It has also been long suspected that the smell mainly the result of small fatty-acid, ester and alcohol molecules is generated not directly by hyenas themselves, but rather by bacteria that live in the pouches.
More than 1,000 compounds have been synthesized following the discovery that l-aspartyl-l-phenylalanine methyl ester, which subsequently became known as aspartame, was found to taste sweet.
The resin can be a vinyl ester, epoxy, or polyester, while the reinforcement might be any one of a variety of fibres, ranging from glass through carbon, boron, and a number of proprietary types.
P.E.M. Berthelot, the distinguished French chemist, confirmed this observation in 1879 with liquid systems, when he found that the reaction of organic acids and alcohols, called esterification, is catalyzed by the presence of small amounts of a strong inorganic acid, just as is the reverse process, the hydrolysis of esters (the reaction between an ester and water).
It is also part of thymidylic acid, a nucleotide (a larger structural unit composed of a nucleoside and phosphoric acid), which is a phosphate ester of thymidine.
In the Procion T series, marketed by ICI in 1979, particularly for dyeing cotton in polyester and cotton blends by the Thermosol process (see above Disperse dyeing), the reactive dye is bonded through a phosphonate ester.
However, the presence of aromatic rings (bulky, hexagonal groups of carbon and hydrogen atoms) in the repeating units greatly stiffens the polymer chain by interfering with the rotation of the repeating units around the ester linkages.
Polyester, a class of synthetic polymers built up from multiple chemical repeating units linked together by ester (CO-O) groups.
To the ester-forming monomers are added modifiers consisting of unsaturated oils such as tung oil, linseed oil, or dehydrated castor oil.
Phosphate is ester-linked to carbon 3, while any one of several possible substituents is also linked to the phosphate moiety.
The reaction can be represented as follows: When an unsaturated oil such as tung oil, linseed oil, or dehydrated castor oil is added to the ester-forming compounds, the result is a branched polyester containing fatty-acid side groups.
