Synthetic Amylose

Synthetic amylose, unlike natural amylose, has a narrow molecular weight distribution and an unbranched, linear structure. It is used mostly as a molecular weight marker or a basic reagent in chemical research into enzymatic substrates and derivatives in polymer chemistry. Given its properties as an oxygen barrier, its ability to polarize light, its transparency and biodegradability, we anticipate that it will have industrial uses as a principal component of highly functional films.
Amylose derivatives also have potential for a wide range of applications, including HPLC carriers for chiral compounds.
We have assembled standard samples of a variety of molecular weights.

Chemical structure

Synthetic amylose is a linear polysaccharide made up of α-(1→4) bound D-glucose molecules.

Applied examples

Synthetic amylose has excellent physical properties for use as a raw material in the manufacture of biodegradable film. In addition, its ability to capture other molecules makes it useful in the manufacture of advanced functional materials.

We anticipate that synthetic amylose will find wide application in food, medicine, cosmetics, chemistry and other fields.

Application Advantages of synthetic amylose
Molecular weight marker Unbranched and linear.
Extremely narrow molecular weight distribution in comparison to natural amylose.
Standard samples of various molecular weights are assembled into a set.
Enzyme substrate Suitable for research on substrate specificity of enzymes such as α-amylase, β-amylase, branching enzymes, transferase etc.
HPLC carrier for chiral compounds Amylose derivatives can separate out chiral compounds.
Derivatives Depending on the derivation, you can improve insolubility, make soluble in organic solvents, make waterproof, increase the strength of film, control biodegradability and increase thermoplasticity.
Cast materials
Film, textiles, particles, coatings, gel, sponges, glue
Amylose and its derivatives have excellent casting properties.
Wrapping material, polarized film
Amylose film is strong, airtight and transparent.
It is also highly biodegradable and safe.
Polarized film Amylose is transparent and wraps tightly around iodine molecules*, so it makes a good polarized film.
Wrapping function
Orientation, time-release properties
Amylose can wrap itself around various materials, including flavorings, drugs, surfactants and alcohol.
