Under normal conditions, what is the primary energy source for the brain?

Fructose
Fatty Acids
Galactose
Glucose

The correct answer is: Glucose

The primary energy source for the brain under normal conditions is glucose. Fructose and galactose are simple sugars, but they are not the main energy source for the brain. Fatty acids are not typically used by the brain for energy, as they are mainly used for energy storage in the form of fat. Glucose is the preferred and most efficient source of energy for the brain as it can easily cross the blood-brain barrier and be converted into ATP, the main source of energy for cellular processes.
