Overview of Starch Phosphorylation

Starch is one of the most abundant natural polymers in higher plants and the main source of energy for human beings in the biosphere. At the initial stage of starch synthesis or degradation, glucose is phosphorylated before entering the corresponding enzymatic reaction system. In plants, starch phosphorylation is the only substitution process, which occurs in the synergistic reaction of a series of enzymes and can only be carried out on the branched-chain structure. To some extent, the degree of phosphorylation modification of starch reflects the digestibility of starch, and it is also a special method of Chemical Modification. Generally speaking, starch and starch derivatives are a kind of excellent material with great potential for many uses, so their production has always been the focus of biological research.

Our Technologies

At CD BioGlyco, we have developed a One-Stop Solution to starch phosphorylation, providing a variety of chemical and biological methods for comprehensive analysis of starch phosphorylation.

• Straight chain structure and branch chain structure separation service
  CD BioGlyco provides the two different chain structures of starch separation service. The specific operation methods are the crystallization method, warm water extraction method, salt separation method, and compounding agent separation method.

• Starch phosphorylation modification service
  We use chemical bonds as a bridge to connect starch and phosphate through the R-O-R bond to prepare starch derivatives. Our annual output is as high as 300000 tons.

• Starch phosphorylation detection and analysis services
  We provide nuclear magnetic resonance (NMR), infrared (IR), scanning electron microscope (SEM), mass spectrometry (MS), and gel permeation chromatography (GPC) to analyze the microstructure and molecular weight of the products. On the other hand, we also provide comprehensive analysis of the mechanical properties (universal mechanical tester) and adsorption (thermal conductivity detector-mass spectrometry, TCD-MS) of starch derivatives.
