Outline the features of the molecular structure of the triglyceride shown in Fig. 3.2.
Understand the Problem
The question is asking for an outline of the features of the molecular structure of a triglyceride depicted in a figure, specifically focusing on its composition and structural characteristics.
Answer
The triglyceride has a glycerol backbone with palmitate and oleate fatty acid chains, forming ester bonds.
The triglyceride consists of a glycerol backbone with three fatty acid chains attached via ester bonds. One chain is palmitate (saturated), and the other is oleate (unsaturated), containing a double bond. The structure enables efficient energy storage.
Answer for screen readers
The triglyceride consists of a glycerol backbone with three fatty acid chains attached via ester bonds. One chain is palmitate (saturated), and the other is oleate (unsaturated), containing a double bond. The structure enables efficient energy storage.
More Information
Triglycerides are energy-dense molecules, which makes them vital for energy storage in organisms like migrating birds.
Tips
A common mistake is confusing the saturated and unsaturated fatty acids, which can affect their energy properties.
