Statement Based +4 −1

Given below are two statements

Statement (I) : The compounds acetone, aceto-acetate and B-hydroxybutyrate are known as ketone bodies.
Statement (II) : Ketone bodies are synthesized in muscles and are fat-soluble in nature.

In light of the above statements, choose the most appropriate answer from the options given below.

  • Statement (I) is True: The three physiological compounds designated as ketone bodies are acetoacetate, $\beta$-hydroxybutyrate (3-hydroxybutyrate), and acetone.
  • Statement (II) is False: Ketone bodies are synthesized primarily in the liver (hepatic mitochondrial matrix via ketogenesis), not muscles. Furthermore, acetoacetate and $\beta$-hydroxybutyrate are water-soluble organic acids transported freely in the bloodstream to extrahepatic tissues without requiring albumin carriers.
  • Conclusion: Statement (I) is true but Statement (II) is false.

Correct option: (3) Statement (I) is true but Statement (II) is false.
