Which of the following is a unique characteristic of ketone bodies? A) They are produced exclusively in adipose tissue B) They are directly derived from amino acids C) They can cross the blood-brain barrier D) They are synthesized from carbohydrates
Understand the Problem
The question is asking us to identify a unique characteristic of ketone bodies from the given options. This will require an understanding of biochemistry and the role of ketone bodies in metabolism.
Answer
They can cross the blood-brain barrier.
The unique characteristic of ketone bodies is that they can cross the blood-brain barrier.
Answer for screen readers
The unique characteristic of ketone bodies is that they can cross the blood-brain barrier.
More Information
Ketone bodies are important as an alternative energy source during periods when carbohydrates are not readily available. Their ability to cross the blood-brain barrier allows them to provide the brain with energy when glucose levels are low.
Tips
A common mistake is assuming ketone bodies are directly produced in adipose tissue or derived from amino acids. They are primarily produced in the liver from fatty acids.
