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.

Your supervisor asks to make 300 mL of a 1.0% (w/v) starch solution using a 5% (w/v) stock solution. You have calcuated how much stock solution you need. But, how much water (in mL) will you need to add to the stock to achieve the correct final concentration?
You are given 150 mL of an oil made up of a mixture of 3 fatty acids: palmitoleic acid (C 16:1 (n-7)) erucic acid (C 22:1 (n-9)) stearidonic acid (C 18:4 (n-3)) You know that the 150 mL sample of this oil was prepared by adding 60 mL of palmitoleic acid to 90 mL of a mixture of erucic acid and stearidonic acid. Using a hydrometer you carefully measure the density of the 150 mL sample of oil and your analysis indicates that it has a density of 0.900 g/cm3. The densities of the individual fatty acids are: palmitoleic acid = 0.894 g/cm3 erucic acid = 0.860 g/cm3 stearidonic acid = 0.9334 g/cm3 Can you determine the volumes (in mL) of erucic acid and stearidonic acid in the total volume (150 mL) of the oil mixture?

You will make Nylon-6,10. What does the 6 and 10 refer to? PROCEDURESynthesis of NylonIn a small beaker dissolve ~ 0.5 mL of sebacoyl chloride in 12 mL of ether. In a smalltest tube get ~ 6 mL (~1/4 of a 6 “ test tube) of 1,6-diaminohexane solution in water.In order to form the good polymer fibers, it is best to not mix the solutions. Youshould try to layer one solution on top of the other. First pour the 1,6-diaminohexanesolution into a 100 mL beaker. Then slowly pour the sebacoyl chloride down the sideof the tilted beaker with minimal mixing. At this point you should see two distinctlayers with a white film at the interface. Hook the nylon which forms at the interfacewith a straightened paper clip and pull slowly straight up as high as possible. Thenwrap it around your large beaker and then continue to wind the polymer around tillthe reaction is complete. Rinse your polymer in DI water to remove any salts or acidthat may be present.Weigh your product and characterize it by…
