Quantifying intermolecular interactions as a basis of domain formation in membranes [PDF]

, 2006
Within the last two decades the field of membrane biology has witnessed an increased interest in the function and organization of membrane lipids with a particular focus on the possibility of these to demix into separate domains.

Digalactosyl-diacylglycerol-deficiency lowers the thermal stability of thylakoid membranes [PDF]

, 2010
We investigated the effects of digalactosyl-diacylglycerol (DGDG) on the organization and thermal stability of thylakoid membranes, using wild-type Arabidopsis thaliana and the DGDG-deficient mutant, dgd1. Circular-dichroism measurements reveal that DGDG-

Lipid Polymorphism of the Subchloroplast—Granum and Stroma Thylakoid Membrane—Particles. I. ³¹P-NMR Spectroscopy

Cells, 2021
Build-up of the energized state of thylakoid membranes and the synthesis of ATP are warranted by organizing their bulk lipids into a bilayer. However, the major lipid species of these membranes, monogalactosyldiacylglycerol, is a non-bilayer lipid.

Relevance of the protein macrodipole in the membrane-binding process. Interactions of fatty-acid binding proteins with cationic lipid membranes. [PDF]

PLoS ONE, 2018
The fatty acid-binding proteins L-BABP and Rep1-NCXSQ bind to anionic lipid membranes by electrostatic interactions. According to Molecular Dynamics (MD) simulations, the interaction of the protein macrodipole with the membrane electric field is a ...

An Overview of Lutein in the Lipid Membrane

International Journal of Molecular Sciences, 2023
Lutein, zeaxanthin, and meso-zeaxanthin (a steroisomer of zeaxanthin) are macular pigments. They modify the physical properties of the lipid bilayers in a manner similar to cholesterol. It is not clear if these pigments are directly present in the lipid phase of the membranes, or if they form complexes with specific membrane proteins that retain them ...

Atomic force microscopy and other scanning probe microscopy methods to study nanoscale domains in model lipid membranes

Advances in Physics: X, 2023
The cell membrane is a fundamental biological structure, which is only 6–10 nm thick. It is composed of hundreds of lipid types, which form small and dynamic lipid domains or rafts.

Membrane curvature sorts lipids [PDF]

The EMBO Reports, 2005
The enrichment of sphingolipids and cholesterol in the mammalian plasma membrane, and unsaturated phosphatidylcholine (PC) in the endoplasmic reticulum, requires lipid sorting in the Golgi apparatus. Most sphingolipids are synthesized in the Golgi lumen (Holthuis & Levine, 2005).
