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.

Iman has a mixture of two compounds A and B. A is a protein, and B is a lipid. He plans to separate the mixture using a column chromatography technique. He packed the column with amino bonded with siloxane material and use a mixture of 20:80 of water: hexane as the mobile phase. i) Sketch the apparatus set up for the chromatographic technique used by Iman. Use the correct chromatographic terminologies to label all of the apparatus, materials, and phases. ii) Predict the sequence of elution when the mixture was loaded onto the separation column. Justify your answer. iii) After the first compound was eluted, Iman discovered that the second compound was taking too long to pass through the column. Please suggest any strategies that could be used to aid the elution process.
