Why are cell membranes not made of micelles?
Micelles are one a one lipid layer with a hydrophillic head on the outside and hydrophobic tails on the inside. Cell membranes require a phospholipid bi-layer, which is two layers with the hydrophobic tails in the center. It creates a "coating" if you will for the cell. If cells were only made of micelles it wouldn't allow for the separation of the inside contents of the cell. Micelles wouldn't work the same way, they would partially integrate with inner contents of the cell creating a huge mess!
What are the characteristics of micelles?
im in biology classs right kn
What is the reaction of saponification by using ordinary fat?
Soaps make soluble in water fats an oils, forming specific micelles.
What factors affects the viscosity of condensed milk?
== == Condensed milk behaves as non-Newtonian and pseudoplastic liquid . The removal of water causes the concentration of the solids to increase. Because of their relatively high concentration and frequent interactions, the casein micelles contribute largely to the viscosity as the distance between the caseinmicelles has decreased. The casein micelles are stabilized from aggregating by steric and electrostatic stabilization due to k-casein molecules situated on the surface of the micelles and these interactions become stronger.This leads to an increased apparent viscosity and the fluid starts to behave like a shear-thinning non-Newtonian fluid. (if you're happened to be doing FST 3103, please do not take this answer straight, thanks. i took this from A. O. Karlsson, R. Ipsen, K. Schrader and Y. Ardö, Relationship Between Physical Properties of Casein Micelles and Rheology of Skim Milk Concentrate, Journal of Dairy Science, 88:3784-3797, 2005)
Is the end of a soap molecule that attracts and dissolves oily dirt polar?
yes the hydrocarbon ends of the soap attracts to the dirt to form structures called micelles.........................hope this answer will help ppl!

What are clay micelles?
Clay micelles are a type of soil colloid that are very small conglomerations of clay particles that retain a negative charge.
What is a clay micelles?
Micelles is just another name for clay. It is very fine and can cover large areas and provides good water retention.
What do these lipids have a special attraction for?
I believe the answer is micelles.
What is polymeric micelles?
Polymeric micelles are nano-sized colloidal structures formed by the self-assembly of amphiphilic block copolymers in aqueous solutions. They generally consist of a hydrophobic core and a hydrophilic shell, allowing them to solubilize hydrophobic drugs and deliver them to target sites in the body. Polymeric micelles have shown promise as drug delivery systems due to their stability, biocompatibility, and ability to enhance drug solubility and circulation time.
Spherical complexes of emulsified fats are known as?
micelles

Why micelles are not formed in ethanol?
dirt particles are soluble in ethanol
Do phospholipids contain polar tails and nonpolar head groups?
The compound with both a non-polar tail and a polar head is called an amphiphilic molecule. An amphiphilic molecule can form micelles. These such micelles is how detergents dissolve dirt. A big example of micelles are phospholipids.
What are phospholipids that tend to form tiny droplets with hydrophobic tails buried inside called?
micelles
How do floor cleaners act on dirt or grease?
Detergent type floor cleaners, which are probably the most common kind, act on dirt or grease by sequestering the dirt or grease in micro-structures called micelles that are spontaneously formed in the cleaners because of their content of molecules that are polar on one end and nonpolar on the other. In micelles, the detergen molecules orient with their polar ends outside and nonpolar ends inside, and the nonpolar interior of the micelles can therefore dissolve the nonpolar dirt and grease molecules to a greater extent than can plain water. Because of the small size of the micelles, they remain suspended in the water long enough to be discarded along with the water in which they are suspended after a floor has been cleaned.
