In colloidal chemistry, the critical micelle concentration (CMC) of a surfactant is one of the parameters in the Gibbs free energy of micellization. The concentration at which the monomeric surfactants self-assemble into thermodynamically stable aggregates is the CMC.
The formation of micelles can be understood using thermodynamics: Micelles can form spontaneously because of a balance between entropy and enthalpy. In water, the hydrophobic effect is the driving force for micelle formation, despite the fact that assembling surfactant molecules is unfavorable in terms of both enthalpy and entropy of the system ...
In 1976, the fundamental theory for understanding the mechanism of micelle formation was developed by Tanford's free energy model. [18] Apart from integrating all relevant physicochemical elements and explaining the growth of micells, he provided a comprehensive reasoning of why micelles are finite in terms of opposing interactional forces. [19 ...
The lipid bilayer is very thin compared to its lateral dimensions. If a typical mammalian cell (diameter ~10 micrometers) were magnified to the size of a watermelon (~1 ft/30 cm), the lipid bilayer making up the plasma membrane would be about as thick as a piece of office paper. Despite being only a few nanometers thick, the bilayer is composed ...
Formation and examples of membraneless organelles. In biochemistry, biomolecular condensates are a class of membrane-less organelles and organelle subdomains, which carry out specialized functions within the cell. Unlike many organelles, biomolecular condensate composition is not controlled by a bounding membrane.
Sunday's Week 12 NFL games includes several intriguing matchups that will dictate the direction the NFC West race heads as the playoffs near.
Every Christmas season, letters to Santa flood in from kids around the world — but in Santa Claus, Indiana, volunteers become Santa’s elves to ensure every child gets a reply.. This small town ...
James Harden moved into second place on the NBA's career 3-point list and had 20 points and 11 assists to help the Los Angeles Clippers beat the Utah Jazz 116-105 on Sunday night to end a three ...
