Lipids with long and saturated fatty acids (for example, sphingolipids) make membranes thicker and less fluid owing to the tight packing of their hydrophobic tails and stronger lipid–lipid ...

Lipid membranes, which form the outer layer of cells, can be engineered to influence cellular functions. For example, adjusting the permeability of the membrane can improve drug delivery. Adding ...

Lipids, or fats, are essential to life. They form the membranes around cells, protecting them from the outside. In nature, there is an enormous diversity of lipids, with each organism having its own ...

The lipid composition of cell membranes is asymmetric: ... 'For example, when lipids that are otherwise located on the inside of the membrane are present on the outside this can serve as a signal ...

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows. This lipid abundance asymmetry is enabled by the unique properties of ...

Non-vesicular lipid transport between intracellular membranes can be mediated by spontaneous lipid transfer or lipid-transfer proteins (LTPs) and is crucial for maintaining the identities of ...

Archaeal enzyme that produces membrane lipids is spectacularly promiscuous. University of Groningen. Journal Journal of Biological Chemistry DOI 10.1016/j.jbc.2021.100691 ...

Lipid kinases are enzymes that play a critical role in both cell signalling and membrane trafficking by phosphorylating lipid ...

The TMEM16 family of membrane proteins was hailed as representing the elusive calcium-activated chloride channels. However, the majority of the family members turned out to be scramblases, proteins ...

Cholesterol, for example, plays a critical receptor role in the channel forming ability of the polyene antifungal agents nystatin and amphotericin B as well as the Clostridial perfringolysin O ...

If you cool down a lipid membrane, for example, the molecules move more slowly, “and then eventually they’ll just lock together,” Winnikoff said, as when you put olive oil in the fridge.
