ester

(ˈɛstə)
n
(Chemistry) chem any of a class of compounds produced by reaction between acids and alcohols with the elimination of water. Esters with low molecular weights, such as ethyl acetate, are usually volatile fragrant liquids; fats are solid esters
[C19: from German, probably a contraction of Essigäther acetic ether, from Essig vinegar (ultimately from Latin acētum) + Äther ether]

Six reversed C-glycopeptidomimetics were prepared using Passerini reaction; a three components reaction of aldehyde, carboxylic acid and isonitrile to furnish amide ester linkage Scheme-1.
The compound A series exhibited a larger single phase region than the compound B series due to the somewhat higher polarity of the ester linkage, which is less soluble in the nonpolar PS compared to the ether group.
TBT-SPC paints are based on an acrylic polymer with TBT groups bonded onto the polymer backbone by an ester linkage, where hydrolysis reaction takes place.
Quantifying functional coatings efficacy in a laboratory setting was performed using the indicator, 4-nitrophenyl acetate (pNp-OAc) possessing an ester linkage. The catalytic reaction rate using pNP-OAc was monitored using UV absorption at 401 nm and these values correspond directly with the degree of chemical conversion versus time while monitoring for the absorbance of the hydrolyzed product p-Nitrophenyl.
As shown in Figure 4, after esterification, there is a shift in the peak at 1710 [cm.sup.-1], which is characteristic of FAs, to 1742 [cm.sup.-1] which corresponds to the ester linkage, confirming the formation of ester groups.
The synthesis of analogous ester and amide series will give further insight into the importance of the ester linkage for bioactivity.
It is subjected to biodegradation, because of the susceptibility of its aliphatic ester linkage to hydrolysis.
A similar approach involves the use of an azidocarboxylic acid to couple, via an ester linkage, with a BODIPY containing a hydroxyl group, which was obtained from the deacetylation of a commercialy available material (Figure 28).
Presumably, if ubiquitination on KR-TCR[alpha] was solely attached via an ester linkage, mild alkaline treatment should lead to complete hydrolysis of this bond.
However, both DOP and chlorogenic acid gave reliable calculation of CAEs by the UV method standardized to the DOP molecule by by correcting the UV absorption to equal 2.5 double bonds per ester linkage. This meant that DOP could be used to quantify CAEs containing 2 esters or one ester by dividing by 2.
What is not well understood is the mechanism of attachment to the acceptor alcohol forming the necessary ester linkage (in the case of ferulates in grasses the C5 hydroxyl of arabinosyl substitutions on arabinoxylans).
This data compensated 18 DBE, the remaining one was attributed to an ester linkage between two units i.e 1,4-dicarboxylic acid and glycol.
