Work Step by Step
A triglyceride has the prefix "tri," which means three. This refers to the three fatty acids that are part of the molecule. The second part of the word, "glyceride," simply refers to the glycerol that is also part of the molecule. Therefore, a triglyceride simply consists of a glycerol with three fatty acids. The other answer choices describe DNA, polysaccharides, and amino acids.
