Special Issue Information
Dear Colleagues,
Polysaccharides are a type of macromolecule that are found in almost all living beings on the planet (except for viruses). These molecules are best known for their structural properties (such as chitin and cellulose) and energetic properties (such as starch and glycogen). However, the study of polysaccharides goes far beyond this. Due to their high biocompatibility, polysaccharides from different sources are being evaluated as bioactive agents for various conditions, and some are already being used as drugs. One example is heparin, a sulfated polysaccharide that has been used as an anticoagulant drug for over 80 years. Moreover, polysaccharides are structurally diverse in terms of their size, type of linkage between monosaccharides, presence of branching, types of substituents, and other factors, all of which influence their activities. The presence of several hydroxyl groups in polysaccharides, as well as their solubility in water and other solvents, makes them targets for chemical modifications. These modifications increase their potential as bioactive molecules and enable polysaccharides and their derivative molecules to be used to produce different biomaterials, including nanomaterials. In recent years, bioinformatics studies with polysaccharides have also been developed, which is increasing the biotechnological potential of these molecules.
In this scenario, this Special Issue presents unpublished studies on natural polysaccharides and their derivatives, as well as review articles on this topic. As guest editors for this Special Issue, we would like to invite you to present your data regarding the study of polysaccharides obtained from different organisms, as well as their derivatives. We welcome studies ranging from the isolation and purification of these molecules to their structural characterization, evaluation of biological, pharmacological, nutraceutical, and biotechnological properties, and proposition of mechanisms of action, including in silico studies.

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. Molecules 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.
