Problem- A common structural feature of membrane lipids is their amphipathic nature. For example, in phosphatidylcholine, the two fatty acid chains are hydrophobic and the phosphocholine head group is hydrophilic. For each of the following membrane lipids, name the components that serve as the hydrophobic and hydrophilic units: (a) phosphatidylethanolamine; (b) sphingomyelin; (c) galactosylcerebroside; (d) ganglioside; (e) cholestrol.
I desire help for above question. Illustrate each step for the above problem.
Think back to what you learned in this course about solutions and intermolecular forces. Why don't these to "mix" together (in other words, make a homogenous solution) when combined. Why do they separate into layers
