Derivatization occurs with a carboxylic acid.

The synthetic method results in the formation of o-naphthoquinone derivatives.

A process is disclosed for regenerating or derivatizing cellulose.

The process permits the regeneration or derivatization of cellulose having a high degree of polymerization.

A process for aromatizing a hydrocarbon using said catalyst composition.

Adding water can also sustain high conversions of HEP, minimize heavies formation, and improve selectivity to NVP.

The formation of acetal derivatives illustrates how subtle changes may alter this selectivity.

EC 2.3.1.Coenzyme A Ligases: Enzymes that catalyze the formation of acyl-CoA derivatives.

There is provided inter alia a method of covalently attaching an amine derivatizing agent to a glutamine of a first polypeptide.

In a further aspect, the process of the present invention includes a step of removing ketone by-products be derivatization.

The process makes use of a treatment, which allows removing an impurity present in the reagent l-acetoxyethyl bromide and responsible for the formation of cefuroxime dimeric derivatives.

Novel fluorescent derivitization reagents are described that are suitable for coupling to biomolecules that contain aldehyde or ketone functional groups.

The method includes adding an amine derivatizing agent, a transglutaminase a first polypeptide which includes a glutamine, and a co-solvent to a reaction mixture.

The ferrocene compound is extremely useful as an agent for derivative formation when a VD compound is determined by LC/ESI-MS/MS.

The use of recombinant enzyme libraries enables one to obtain enzymes that catalyze the formation of organic molecule derivatives that could not otherwise be made using only naturally occurring enzymes.
