Concept explainers

Micelles and Biological Membrane

Micelles are the type of lipid molecules that organize themselves in spherical shape in aqueous solutions. The production of the micelle is a reply to the amphipathic behavior of fatty acids. It means that they consist of both hydrophobic regions and hydrophilic regions. In micelles, polar head groups (hydrophilic groups) produce an outer layer associated with water whereas nonpolar tails (hydrophobic groups) are organized in the interior.

Question

Which of the following statement is false?

Component with the strong attraction to the support move more slowly than component with weak attraction.

Chromatography technique used to separate only colored compounds.

On TLC, single spot does not mean or guarantee a single substance (compound).

Iodine vapor and UV- lamp are methods used for visualization uncolored compounds.
