What term best describes region “B” of the phospholipid model above?

Answers

Answer:

Explanation: The phospholipid has a chagred head (Phosphate region) and hydrophobic tails. Lipids are usually nonpolar and hydrophobic. That is why the tails are oriented towards the interior of the membrane.

The two parts 3 and 4 in the region B of the phospholipid model are 3- saturated fatty acids and 4- unsaturated fatty acids.

What is phospholipid model ?

Phospholipids are a class of lipids having significant role in the construction of cell membranes. It is composed of a hydrophilic head with a phosphate group and a hydrophobic tail with fatty acids end.

The fatty acids present in the phospholipid bilayer , are of two types, Saturated and unsaturated. Fatty acids chains without any double bonds or triple bonds are called saturated fatty acid.

Whereas, fatty acid chain with double bonds or triple bond are called unsaturated fatty acids. These two fatty acids chain creates the hydrophobic tail of the phospholipid bilayer.

Hence the region marked as B is saturated and unsaturated fatty acids.
