Topic:Micelle
Micelles are aggregates of surfactant molecules dispersed in a liquid colloid that have applications in various fields, including equine nutrition and drug delivery. In horses, micelles can enhance the bioavailability of certain nutrients and medications by facilitating their absorption in the gastrointestinal tract. These structures can encapsulate hydrophobic compounds, improving their solubility and stability. Research in equine science investigates the formulation and efficacy of micelle-based supplements and therapeutics, exploring their potential benefits and limitations. This page compiles peer-reviewed research studies and scholarly articles that examine the formation, function, and application of micelles in equine health and nutrition.
The comparison of pepsin and trypsin action on goat, cow, mare and human caseins. The degree of proteolysis of micellar caseins of human, goat's, mare's and two breeds (Black&White and Red Polish) of cow's milk was compared for pepsin and trypsin action in vitro. Human and goat's caseins were hydrolysed in 100% and 96%, respectively, mare's casein--92%, Black&White cow's casein--90%, Red Polish cow's casein--76%. The differences can be related to the micelle structure, especially to the prevalence of beta casein in the human and goat's casein. The significant dissimilarity between the two breeds of investigated cows is surprising and indicates a different geometry o...
Studies on iron uptake and micelle formation in ferritin and apoferritin. Iron uptake and micelle formation in ferritin and apoferritin have been followed both spectrophotometrically and by means of sedimentation velocity experiments. Information was thus obtained on the molecular weight distribution of the reconstitution product. To achieve incorporation 'native' ferritin (whole ferritin as purified from horse spleen), 'native' apoferritin (apoferritin prepared by fractionation of ferritin preparations) and 'reduced' apoferritin (apoferritin prepared by reduction of ferritin by dithionite or ascorbic acid) have been incubated with ferrous salts in the presence of o...
The release of iron from horse spleen ferritin to 1,10-phenanthroline. The rate of release of iron to 1,10-phenanthroline from ferritin fractions of different iron contents has been studied. The experimental results could be interpreted by a simple hypothetical model of the shape of the hydrous ferric oxide micelle at different iron contents, and reasonable correlation obtained between the rate of release and the calculated micelle surface areas. Initial rates of release did not correlate significantly with protein concentration.
