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 ...

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, ...

Lipids are essential building blocks of cell membranes, which control the exchange of substances and energy between a cell and its environment. Developed at the Moscow Institute of Physics and ...

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 ...

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 ...

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

Scientists have developed a method for analysing the structure of lipid nanoparticles that could be used to improve vaccine and drug delivery, targeting a wide range of health issues. (Nanowerk News) ...

Oregon Health & Science University, in collaboration with Oregon State University, has discovered the structural organization and protein components of a lipid-transfer complex known as LPD-3.

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 ...
