I. Nylon 6-6 is a condensation polymer. The last two lab handouts pointed out that "condensation reactions are extremely common among a variety of organic functional groups." Pick two appropriate functional groups (your choice) and draw structures to show the condensation reaction between them. Identify the functional groups that are reacting, as well as the linkage formed by the condensation. 2. Rather than use a carboxylic acid for the nylon condensation, you'll use the more reactive acid chloride. This must...

Lo 8: Properties of the Plasma Membrane 1) Draw the structure of a phospholipid and label the three parts: Glycerol backbone, fatty acid tails and phosphate head group. Label which regions are hydrophobic and which are hydrophilic. Be able to explain WHY they have the property they do (think of their chemical make up-look it up if you need a reminder). 2) Describe two properties that affect membrane fluidity? Draw a representation of how each property affects membrane fluidity. Explain...
