Antioxidant Peptides from Marine Organisms: Structural Insights, Functional Mechanisms, and Sustainable Applications

Dear Colleagues,

In recent years, there have been an increasing number of reports on the preparation, structure, and activity of marine antioxidant peptides. These peptides, derived from the vast biodiversity of marine ecosystems including fish, algae, mollusks, and microorganisms, represent an untapped reservoir of bioactive compounds shaped by evolutionary adaptation to diverse marine environments. New methods and technologies such as computer-aided mathematical models (molecular docking, QSAR studies, etc.), bioinformatics tools, and real-time-updated protein databases have been widely explored and studied for marine antioxidant peptides.

In addition, marine antioxidant peptides not only retain high nutritional value, but also enhance the treatment of oxidation-related diseases, delay the oxidation of food, and thereby improve quality of life. Their structural and functional diversity is intrinsically linked to the genetic and organismic diversity of their marine sources, offering unique opportunities to understand how biodiversity contributes to bioactive compound discovery.

Given the widespread and current interest in this topic, this Special Issue joins Antioxidants and Diversity with the aim of publishing recent research on the following topics of interest:

• Using new methods and technologies to produce antioxidant peptides from marine proteins;
• Comprehensive studies of the structure–activity relationship of marine antioxidant peptides;
• Understanding the antioxidant mechanism and the verification of health benefits in vivo;
• Exploring the biodiversity basis of marine peptide bioactivity;
• Sustainable utilization of marine biological resources for peptide discovery.

We particularly encourage studies that reveal the connections between marine biodiversity and peptide bioactivity, as well as research addressing the conservation and sustainable use of marine genetic resources.

You may choose our Joint Special Issue in Antioxidants.

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 250 words) can be sent to the Editorial Office for assessment.

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. Diversity is an international peer-reviewed open access monthly 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 2100 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.
