The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Structure of Gel Phase DMPC Determined by X-Ray Diffraction (2002, background): “A much more accurate value of KA 234 23 dyn/cm was obtained for the fluid L phase of DMPC (Rawicz et al., 2000).”
The Various Roles of Fatty Acids (2018, background): “By decreasing membrane bending rigidity [142,143], DHA in phospholipids was shown to promote rapid endocytosis [141] and arachidonic acid (20:4ω6) in membrane phospholipid of hepatocytes and enterocytes was shown to facilitate transport of triglycerides into the lumen of the endoplasmic reticulum [1”
Controlled vesicle deformation and lysis by single oscillating bubbles (2003, methodology): “We chose giant unilamellar lipid vesicles (‘artificial cells’ consisting only of a lipid bilayer membrane) as our primary object of study because of their well-defined mechanical propertie”
Structure of Fully Hydrated Fluid Phase Lipid Bilayers with Monounsaturated Chains (2006, result): “Our results for material properties were the same for these two samples, which is consistent with Rawicz et al. (2000) who reported the same K C values for SOPC and OPPC.”
Bilayer thickness and membrane protein function: an energetic perspective. (2007, background): “The energy required to change the lipid shape causes a stress in the bilayer, with an energy density of (Kc/2) · c 2 0, where Kc ≈ 20– 25 kBT for liquid-crystalline phospholipid bilayers that have saturated or monounsaturated acyl chains (98).”
