Researchers report the structure of a key long-chain lipid in the tear film lipid layer, which prevents tears from drying out. Their finding may be used to improve treatments for dry eye. As anyone ...

Minor changes in moisture level can promote lipid molecules to reorganize themselves in biomaterial or biomembranes. This can ...

Crenarchaeol is a large, closed-loop lipid that is present in the membranes of ammonium-oxidizing archaea. In comparison to other archaeal membrane lipids, crenarchaeol is very complex and, so far, ...

As anyone who has experienced an annoying alternation between dry and watery eyes can confirm, tears alone aren't enough to keep the eye from drying out. A microscopically thin film of oils known as ...

Interest in lipid nanoparticles (LNPs) as delivery vehicles for precision therapies in genetic diseases and cancers remains at an all-time high. Now, scientists from the University of Pennsylvania, ...

Membrane-integrated type II phosphatidic acid phosphatases (PAP2s) are important for numerous bacterial to human biological processes, including glucose transport, lipid metabolism, and signaling.

Phosphatidylinositol 3-kinase, or PI3K for short, is a family of lipid kinases that plays a key role in the human body, performing functions such as cell division, metabolism, and cell growth. While ...

Using cutting-edge electron microscopy, researchers from Aarhus University have determined the first structures of a lipid-flippase. The discoveries provide a better understanding of the basics of how ...

The structure of lipid nanoparticles is similar to that of nanoemulsions. Typically, the size of nanoparticles varies between 50 and 1000 nm. It is different from nanoemulsions in that the lipid core ...
