Malnutrition, particularly protein undernutrition, contributes to the occurrence of osteoporotic fracture by lowering bone mass. In this study, the effects of dietary protein on bone mineral density and body weight in protein undernutrition were compared between gelatin and milk casein. When mice were fed for 10 wk with a low protein diet containing 10(%) casein or 6% casein +4% gelatin, there ...

A new type of cow’s milk, called A2 has appeared in the dairy aisles supermarkets recent years. Cows’ milk generally contains two major types beta-casein as A1 and types, although there are 13 genetic variants ?-casein: A1, A2, A3, A4, B, C, D, E, F, H1, H2, I G. Studies have shown that ?-casein may be harmful, is a safer choice for human health especially infant nutrition health. The cow repor...

more than 80% of the total milk protein contains caseins that are to forms α-s1, α-s2, β-casein and kappa casein. kappa casein is smaller than other milk proteins but due to have a role in size and stability of micelles. the present study describes polymorphism of kappa casein gene. this is the first study of kappa casein gene polymorphism in najdi cattle of iran. we used the polymerase chain r...

Clathrate hydrates are supramolecular solids in which small, hydrophobic species are trapped inside a network of hydrogen-bonded water cages. While the best known examples are the natural gas hydrates, similar crystalline structures can also be formed from salts of tetra-n-butylammonium hydroxide (TBAOH). When TBAOH is reacted with medium to long chain carboxylic acids it produces surfactant co...

Intradiffusion coefficients of sodium alkylsulfonates [CH3-(CH2)n-1SO-3 Na+, CnSNa] (n = 5-9, 11) in mixtures with heavy water were measured by the PGSE-NMR technique at 25 degrees C. A slope change in the experimental trends permits the determination of the critical micelle concentration (CMC). In the micellar composition range, solubilized TMS molecules were used to determine the micelle intr...

Photo-controlled metal-ion (Zn(2+) and Cd(2+)) release in aqueous micelle solution (tris-HCl, pH = 7.4) has been described using 2-((2-mercaptophenylimino)methyl) phenol as ligand. It is found that both the ligand-Zn complex (1) and the ligand-Cd complex (2) are stable in micelle solution, and Zn(2+) (Cd(2+)) can be released from the complex with 365 nm light trigger. Accompanying the metal-ion...

2014 The effect of temperature on the aggregation behaviour of nonionic surfactants in aqueous solution has been investigated by means of transient fluorescence probing (intramicellar excimer formation by pyrene). For surfactants of the C12H25En type (E = ethyleneoxide group, n = 6, 8, 9) the number average aggregation number N of the micelle is nearly independent of the temperature T when T is...

Sodium dodecyl sulfate (SDS) surfactants form micelles when dissolved in water. These are formed of a hydrocarbon core and hydrophilic ionic surface. The small-angle neutron scattering (SANS) technique was used with deuterated water (D2O) in order to characterize the micelle structure. Micelles were found to be slightly compressed (oblate ellipsoids) and their sizes shrink with increasing tempe...

Removal of Cr(VI) from aqueous solutions under different conditions was investigated using either clay (montmorillonite) or micelle-clay complex, the last obtained by adsorbing critical micelle concentration of octadecyltrimethylammonium ions onto montmorillonite. Batch experiments showed the effects of contact time, adsorbent dosage, and pH on the removal efficiency of Cr(VI) from aqueous solu...
