Abstract:
This paper reports the chemoenzymatic synthesis of an amylose-grafted cellulose. A maltoheptaose was chemically introduced to the amine-functionalized cellulose by reductive amination to produce the maltoheptaose-grafted cellulose. Then, the phosphorylase-catalyzed enzymatic polymerization of glucose 1-phosphate from the graft-chain ends on the cellulose derivative was performed, giving the amylose-grafted cellulose. The obtained material is shown to form gels and films. The dry and wet cycles of the materials were repeated.

Hydrolysis
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...
