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.

John wanted to determine the protein content of his blood. To do so, he obtained 1.00 mL of blood, and diluted it to 10.00 mL. From that solution, he subjected 1.00 mL to Kjeldahl analysis. After digestion, the liberated NH3 was distilled in a flask containing exactly 25.00 mL of 0.0150 M H3BO3. Titration requires 5.85 mL of standard 0.0150 M NaOH to reach the desired endpoint. If a typical blood sample contains 15.45 g N per 100 g protein, calculate the protein content (in g/mL) in the sample of John’s blood.
