The term which best describes the region "b" of the phospholipid model in the attached image (below) is: Hydrophobic.
Phospholipids are also referred to as phosphatides and they are a type of lipid whose molecule comprises the following:
- A hydrophilic "head" that contains a phosphate group.
- Two (2) hydrophobic "tails" joined by an alcohol residue and that are mainly derived from fatty acids.
This ultimately implies that, a large potion of the cell (plasma) membrane is made up of lipids, which are mainly phospholipids and they control the movement of large hydrophilic molecules such as alkanes, oils, and fats.
In conclusion, hydrophobic is a term that is used to describe the tail or lower part of a phospholipid model, which is the "b" region in the image attached below.
