chain extension

The reaction is used in carbohydrate chemistry as a chain extension method for example that of D-xylose.

Chain extension of 1 was performed by simply increasing the C-N bond distance.

Two rounds of chain extension with malonate follow.

This reaction is known as chain extension reaction.

So my final challenge is for PSL to increase its reach through the supply chain extension.

The differences are that hydroformylation promotes chain extension, and uses a rhodium-based catalyst system.

GTS compact About the size of a shoe box with the fully enclosed chain extension housed within a tough aluminium shaft.

If rifamycin binds the polymerase after the chain extension process has started, no inhibition is observed on the biosynthesis, consistent with a steric-occlusion mechanism.

The first mechanism involved a chain extension reaction by cinnamic acid and 5 malonyl-CoA molecules that eventually arylized into a curcuminoid.

The flavonoids are products from a cinnamoyl-CoA starter unit, with chain extension using three molecules of malonyl-CoA.

During this treatment, commonly referred to a postcure, the molecular weight increases through chain extension and the polymer gets much stronger and more chemically resistant.

Chain extension of 4-hydroxycinnamoyl-CoA with three molecules of malonyl-CoA gives initially a polyketide (Figure 1), which can be folded.

The Exmouth Dock Railway was incorporated in 1864, a 40 chain extension of the Exeter and Exmouth company.

Synthesis of α-hydroxy carbonyl compounds is most commonly accomplished by either chain extension or oxidation of carbonyl compounds.

An NRPS module introduces a glycine residue into the growing polyketide chain, followed by two more rounds of chain extension with malonate.

Because polyketide synthesis is similar to fatty acid synthesis, during chain extension the molecule may undergo reduction of the ketone, dehydration, and reduction of the olefin.

Prepolymer systems can be hand or machine mixed and additives such as catalysts, flame retardants, plasticisers, fillers etc are typically blended into the prepolymer prior to chain extension.

The results indicate that 1 is assembled via the polyketide pathway from 3-amino-5-hydroxybenzoic acid (2) as the starter unit (mC7N unit) plus seven propionate and six acetate chain extension units.

This polymerase breaks when reaching erroneous uracil in DNA from the chain extension and, through this readahead function, fewer defective DNA clones are synthesized.

The Doering-LaFlamme allene synthesis entails the conversion of alkenes to allenes (a chain extension) with magnesium or sodium metal through initial reaction of the alkene with dichlorocarbene.

The reactions represent a means of branching and chain extension in the carbohydrate series and lead to the incorporation of highly functionalized carbon units at predetermined sites in the sugar molecule.

The biosynthesis of catechin begins with a 4-hydroxycinnamoyl CoA starter unit which undergoes chain extension by the addition of three malonyl-CoAs through a PKSIII pathway.

As with other living radical polymerization techniques, RAFT allows chain extension of a polymer of one monomer with a second type of polymer to yield a block copolymer.

Another approach involves the synthesis of reactive telechelic oligomers containing functional end groups capable of reacting with each other, polymerization of the oligomer gives higher molecular weight, referred to as chain extension.

BGI offers innovative and competitive investment products in both the advanced active and index categories as well as value chain extensions such as securities lending, cash management, securities crossing and portfolio restructuring.
