Question
Chapter 3.5, Problem 1CS
Summary Introduction
To determine: The model for the structure of the lipid droplet with reference to the figure 3.11 (b) given in the textbook. Also, indicate neutral lipids with blue dots and proteins as green blobs.
Introduction: Inside the cells of human beings, lipids are always stored in specialized structures called lipid droplets. Phospholipids are those which contain a phosphate group in addition to the triglycerides.

Liposomes are simply vesicles with a phospholipid bilayer that contain an inner aqueous compartment. Hydrophilic compounds could be carried in the buffer inside the liposome or hydrophobic drugs within the membrane itself. For instance, the Moderna and Pfizer mRNA vaccines actually use liposome technology to deliver the SARS-CoV-2 spike mRNA to human cells. The liposomes fuse with the plasma membrane allowing the contents of the liposome to enter the cytosol of cells. Of course, once the mRNA is in the cytosol is can be translated to protein on a ribosome. Explain why nucleic acid won’t get through the plasma membrane on its own.
