• copolymers
  • The end-decorated homopolymer poly(ε-caprolactone)-ferrocene threaded onto a β-cyclodextrin-functionalized main-chain polymer can form a class of amphiphilic noncovalent graft copolymers based on the host-guest interactions of the terminal groups on the side chains. (rsc.org)
  • en] The morphology of micelles formed by two poly(2-vinylpyridine)-block-poly(ethylene oxide) (P2VP-b-PEO) copolymers has been studied in phosphate-buffered water by dynamic light scattering and transmission electron microscopy. (uliege.be)
  • IUPAC definition Micelle: Particle of colloidal dimensions that exists in equilibrium with the molecules or ions in solution from which it is formed.Micelle (polymers): Organized auto-assembly formed in a liquid and composed of amphiphilic macromolecules, in general amphiphilic di- or tri-block copolymers made of solvophilic and solvophobic blocks. (wikipedia.org)
  • For example, block copolymers often form micelles, as will star polymers and branched polymers. (wikipedia.org)
  • Commercially relevant copolymers include acrylonitrile butadiene styrene (ABS), styrene/butadiene co-polymer (SBR), nitrile rubber, styrene-acrylonitrile, styrene-isoprene-styrene (SIS) and ethylene-vinyl acetate, all formed by chain-growth polymerization. (wikipedia.org)
  • Stereoblock copolymers A special structure can be formed from one monomer where now the distinguishing feature is the tacticity of each block. (wikipedia.org)
  • bile salts
  • When these bile salts are secreted into the lumen of the intestine, bacterial partial dehydroxylation and removal of the glycine and taurine groups forms the secondary bile acids, deoxycholic acid and lithocholic acid. (wikipedia.org)
  • Absorption of lycopene requires that it be combined with bile salts and fat to form micelles. (wikipedia.org)
  • The dispersion of food fat into micelles provides a greatly increased surface area for the action of the enzyme pancreatic lipase, which actually digests the triglycerides, and is able to reach the fatty core through gaps between the bile salts. (wikipedia.org)
  • molecules
  • This structure formed is more highly ordered than free water molecules due to the water molecules arranging themselves to interact as much as possible with themselves, and thus results in a higher entropic state which causes non-polar molecules to clump together to reduce the surface area exposed to water and decrease the entropy of the system. (wikipedia.org)
  • A micelle (/maɪˈsɛl/) or micella (/maɪˈsɛlə/) (plural micelles or micellae, respectively) is an aggregate (or supramolecular assembly) of surfactant molecules dispersed in a liquid colloid. (wikipedia.org)
  • However, the lipophilic "tails" of surfactant molecules have less contact with water when they are part of a micelle-this being the basis for the energetic drive for micelle formation. (wikipedia.org)
  • The water molecules that form the "cage" (or solvation shell) have restricted mobility. (wikipedia.org)
  • duodenum
  • The pKa of the unconjugated bile acids are between 5 and 6.5, and the pH of the duodenum ranges between 3 and 5, so when unconjugated bile acids are in the duodenum, they are almost always protonated (HA form), which makes them relatively insoluble in water. (wikipedia.org)
  • Thus conjugated bile acids are almost always in their deprotonated (A-) form in the duodenum, which makes them much more water-soluble and much more able to fulfil their physiologic function of emulsifying fats. (wikipedia.org)
  • Ordinarily, the micelles in the duodenum have a diameter around 14-33 μm. (wikipedia.org)
  • CTAB
  • In vivo, CTAB ablated tumor-forming capacity of FaDu cells and delayed growth of established tumors. (wikipedia.org)
  • Glycoproteins form broad, fuzzy bands in SDS-PAGE (Laemmli-electrophoresis) because of their broad distribution of negative charges.Using positively charged detergents such as CTAB will avoid issues associated with glycoproteins. (wikipedia.org)
  • Therefore
  • Because the rate of addition of the second monomer influences the polymerization and therefore properties of the formed polymer, continuous information about the polymer composition is vital. (wikipedia.org)
  • glycine
  • Like other bile acids, it can be conjugated in the liver with taurine or glycine, forming taurochenodeoxycholate or glycochenodeoxycholate. (wikipedia.org)
  • Prior to secreting any of the bile acids (primary or secondary, see below), liver cells conjugate them with one of two amino acids, glycine or taurine, to form a total of 8 possible conjugated bile acids. (wikipedia.org)
  • nonpolar
  • A hydrocarbon chain or a similar nonpolar region of a large molecule is incapable of forming hydrogen bonds with water. (wikipedia.org)
  • mixture
  • If the bacteria are left in the milk too long, the pH lowers further, the micelles attain a positive charge, and the mixture returns to liquid form. (wikipedia.org)
  • molecule
  • In its natural, all-trans form, the molecule is long and straight, constrained by its system of eleven conjugated double bonds. (wikipedia.org)
  • known
  • This type of micelle is known as a normal-phase micelle (oil-in-water micelle). (wikipedia.org)
  • Popular in the Jewish cuisine of New York City, where it is commonly known as a "schmear", it forms the basis of the bagel and cream cheese, a common open-faced sandwich which also often includes lox, capers, and other ingredients. (wikipedia.org)
  • structure
  • Although the closest counterions partially mask a charged micelle (by up to 90%), the effects of micelle charge affect the structure of the surrounding solvent at appreciable distances from the micelle. (wikipedia.org)
  • example
  • For example, the micelles are, by nature, spatially heterogeneous with a hydrocarbon, nearly anhydrous core and a highly solvated, polar head group. (wikipedia.org)
  • high
  • The use of micelles in high performance liquid chromatography was first introduced by Armstrong and Henry in 1980. (wikipedia.org)
  • study
  • These highly mobile, spontaneously formed clusters came to be called micelles, a term borrowed from biology and popularized by G.S. Hartley in his classic book Paraffin Chain Salts: A Study in Micelle Formation. (wikipedia.org)
  • Different
  • In a subsequent paper the simultaneous, segregated storage of two different chromophores in the different micelle domains was demonstrated, offering potential for use in chemical delivery in fields such as pharmaceuticals, personal care products, and foodstuffs. (wikipedia.org)
  • function
  • The main function of bile acids is to allow digestion of dietary fats and oils by acting as a surfactant that emulsifies them into micelles, allowing them to be colloidally suspended in the chyme before further processing. (wikipedia.org)
  • groups
  • The general form of the polymer is a backbone with functional "pendant groups" that hang off of it. (wikipedia.org)
  • help
  • These micelles form templates that help build up the mesoporous framework. (wikipedia.org)
  • Two forms of nanomedicine that have already been tested in mice and are awaiting human testing will use gold nanoshells to help diagnose and treat cancer, along with liposomes as vaccine adjuvants and drug transport vehicles. (wikipedia.org)
