Special Issue Information
Dear Colleagues,
Lipids comprise a large group of structurally heterogeneous compounds, the majority of which include esters of fatty acids (FAs), with the largest constituents being triacylglycerols (TAGs) and wax esters (WEs). Wax esters are esters of FAs and long-chain alcohols. They have the general formula: R1COOR2, where R1COOH is the FA and R2OH is the long-chain alcohol. The component FAs and alcohols of WEs usually have an even number of carbon atoms ranging from 10 to 36. Waxes are natural lipid mixtures containing ketones, alcohols, aldehydes, long-chain acids, and WEs, with WEs accounting for most of the lipids found in animal waxes. Wax esters are key components of arthropod exoskeletons, sebum covering the mammalian epidermis, and cutin covering the above-ground portions of terrestrial plants. These are extracellular WEs that are water-resistant and protect against pathogens. Although most eukaryotic organisms store energy primarily in the form of TAGs, some species of plants, fish, and zooplankton store energy mostly in the form of WEs inside cells. A major component of the carbon flow through marine food chains is thus WEs. This Special Issue will explore the biochemistry of naturally occurring WEs that have antimicrobial, energy storage, and/or water-resistant functions in a variety of species ranging from bacteria to mammals.

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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
