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.

Topic: Isolation of Crude Ovalbumin from Egg White by Ammonium Sulfate Precipitation (Salting Out) crude ovalbumin was isolated from egg whites of two medium-sized eggs. Egg whites contain about 88.5% water and about 10% proteins, from which ovalbumin is the major component. The eggs were cracked open, and the egg whites were separated carefully from the yolk. Stirring of the egg whites was done to break up the membrane. This was followed by filtration through cheesecloth, where a clear filtrate was obtained. About 40.0 mL of the filtered undiluted egg white was measured, and 0.10 mL of 1 M acetic acid was slowly added for every 1.0 mL of egg white with constant stirring. A turbid mixture with few amounts of white precipitate may be expected to form. These may be removed by filtering the mixture using a cheesecloth. After filtration, 30.0 mL of the filtrate was obtained, and the solution was brought from 0% to 40% saturation by adding the required amount of powdered ammonium sulfate,…
