Special Issue Information

Dear Colleagues,

Carbohydrate polymers are some of the most abundant and important biological macromolecules in nature. Carbohydrate-related polymers can be roughly divided into three categories: (a) polysaccharides found in nature, usually homopolymers or heteropolymers (including cellulose, dextrin, and agarose); (b) naturally derived synthetic polysaccharides, which are polymers containing the main chain of carbohydrates, made by ring-opening polymerization or other methods with monomers made from natural sugars; and (c) sugar polymers (including glycopeptides) are synthetic polymers with monosaccharides or oligosaccharides as side groups. The application of carbohydrate polymers, especially sugar polymers, has attracted significant attention.

This Special Issue mainly covers the preparation, structural modification, biological and chemical synthesis, structural characteristics, biological activity, and potential application of carbohydrate polymers in areas such as bioenergy, bioplastics, biomaterials, nanotechnology, biorefining, drug delivery, food, chemistry, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, and wood.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Hemicellulose extracted by alkali treatment is of interest because of the advantages of its intact sugar structure and high degree of polymerization. However, the hemicellulose extracted by alkali treatment contained more lignin fragments and the presence of a lignin–carbohydrate complex (LCC), which affected the isolation and purification of hemicellulose and its comprehensive utilization. Therefore, the evaluation of the LCC structure of different types of lignocellulosic resources is of great significance. In this study, the LCC structures of hardwoods and Gramineae were enriched in alkaline systems. Information on the composition, structural proportions, and connection patterns of LCC samples was discussed. The similarities and differences between the LCC structures of different units of raw materials were comparatively studied. The results indicated that the monosaccharide fractions were higher in the LCC of Gramineae compared to hardwoods. The composition of the lignin fraction was dominated by G and S units. The phenyl glycosidic (PhGlc) bond is the predominant LCC linkage under alkali-stabilized conditions. In addition, Gramineae PhGlc types are more numerous compared to hardwoods. The results of the study provide insights into the differences in the chemical composition and structural features of LCC in different plants and provide important guidance for the optimization of the process of purifying hemicellulose.
