Collins Dictionary of Biology, 3rd ed. © W. G. Hale, V. A. Saunders, J. P. Margham 2005 es·ter (es'tĕr) An organic compound containing the grouping, -X(O)-O-R (X = carbon, sulfur, phosphorus; R = radical of an alcohol), formed by the elimination of H2O between the ...
Ester Linkage of p-Coumaric Acid in Bamboo Lignin : Holzforschung - International Journal of the Biology, Chemistry, Physics and Technology of WoodTakayoshi Higuchi
(polymerize) under the action of the enzyme DNA polymerase, two of the phosphates are cleaved off leaving only one phosphorous atom between each pair of adjacent sugar molecules. The two ester (diester) bonds in each linkage are Carbon-Oxygen-Phosphorus from the 5’-carbon on one sugar and ...
Nanomaterialsbearing a primary amine group can be reacted withN-hydroxysuccinimide ester (activated carboxylic acid with NHS) and anisothiocyanategroup to form anamide(Figure 1.11a) andthiourealinkages (Figure 1.11b), respectively. Thiourea linkage is more prone to degradation during long-term storage...
The internucleotide linkage formation using N-ethyl-5-phenylisoxazolium fluoroborate (52; equation 36) goes through a similar pathway.71,72 The alkoxyvinyl ester of phosphoric acid (53), prepared by the addition of a phosphodiester to an alkoxyalkyne, is also an active phosphorylating agent.73,...
What small molecule is the byproduct produced from the ester linkage of a fatty acid to glycerol? Triglycerides are used in biochemical systems to store energy; they can be formed from glycerol and fatty The enzymes which are used to convert starch into ethyl alcoh...
a hydrophilic group and fatty acids as lipophilic groups. The carbon chain length and nature of the sugar head group, together with the many possibilities for linkage between the hydrophilic sugar head group and the hydrophobic alkyl chain, contribute to the unique physicochemical properties of sugar...
Fig. 1A demonstrates that dUTPase is also capable of hydrolyzing the imino-linkage of α,β-imino-dUTP, while no detectable hydrolysis of the β-γ bond occurs, i.e. the exclusive specificity of dUTPases for α-β bond cleavage is retained in the reaction with the imino analogue as well....
The slight increase in HDL-C concentration may be due to its linkage with other functional polymorphisms in the promoter area of the gene, which may cause decreased activity of CETP and hence, an increase in HDL-C concentration [29]. Human and transgenic mouse experiments have shown that ...
Lactosylated poly(ethylene glycol)-sirna conjugate through acid-labile β-thiopropionate linkage to construct ph-sensitive polyion complex micelles achieving enhanced gene silencing in hepatoma cells. J. Am. Chem. Soc. 2005, 127, 1624–1625. [Google Scholar] [CrossRef] Lee, S.H.; Gupta, M...
