Problem 4: Identification of another biological molecule

Tutorial to help answer the question

The structure shown in the diagram is an example of a lipid.


If necessary, review the tutorial for question 2 with information on the characteristic properties of different classes of biological molecules.

The feature of this molecule that can be most easily recognized is the three fatty acids with long, hydrophobic tails consisting mostly of repeats of -CH2- groups. The three fatty acids are covalently linked to a glycerol. This compound is a neutral fat of the type used to store reserves of energy in our fatty (adipose) tissues.
