Fatty acids: Are long-chain carboxylic acids. Palmitic acid (C) and arachidonic acid (B) are examples of fatty acids.
Amino acids: Glutamic acid (A) and aspartic acid (E) are amino acids, the building blocks of proteins. They are not fatty acids.
Phospholipid: Lecithin (D) is a type of phospholipid, a major component of cell membranes. While fatty acids are part of the structure of lecithin, lecithin itself is not a fatty acid.
Thus, the compounds that are not fatty acids are A, D, and E.
