The molecules containing hydrophilic phosphate heads and hydrophobic lipid tails are known as phospholipids. These forms of lipids are found in the cellular membranes and perform an important activity by protecting and covering the internal components of the cell.
A reply by a good student will be yes for the question asked by Dr. Haxton, as fats and water are not compatible with each other. The nonpolar molecules like fats do not get mixed with water, and thus, possesses the tendency to travel within the particles that get covered by proteins and phospholipids, which are polar in nature
.
The composition of fats is fatty acid and triglycerides which are hydrophobic in nature. The hydrophobic nature makes it difficult to be transported through the bloodstream.
Therefore body form structures of a single layer of the phospholipids and the apolipoproteins known as the lipoproteins. The hydrophilic portion is present outside whereas the hydrophobic portion is present inside enclosing the fats.
The mutation would cause a(in most cases) new and different polypeptide(protein) to be made so it can cause a different trait. For example a new eye color in fruit fly with mutated dna.
