Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas The number of unshared pairs at atom a is The number of unshared pairs at atom bis The number of unshared...

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...
