Which of the Following is Not a Characteristic of Lipid

Question

Which of the following is not a characteristic of lipid A?
A)Heat stable
B)Toxic in nanogram amounts
C)Weakly immunogenic
D)Neurotoxic

Accepted Answer

Lipid A is not neurotoxic. It is a component of the lipopolysaccharide (LPS) molecule found in the outer membrane of Gram-negative bacteria. Lipid A is heat-stable, toxic in nanogram amounts, and weakly immunogenic. Its toxicity is responsible for the fever, chills, and shock associated with Gram-negative bacterial infections.
