Question

Quizplus · Accepted Answer

Ketone bodies, such as beta-hydroxybutyrate and acetoacetate, are synthesized from acetate units to provide metabolic fuel for the brain and other tissues when carbohydrate intake is low or when the body is in a state of prolonged fasting or intense exercise. Fatty acids can also be used for energy, but they cannot cross the blood-brain barrier, so they cannot be used by the brain as a fuel source. Amino acids are primarily used for protein synthesis, and sterols are precursors to hormones and cell membranes.
