Identify physiological source of cholesterol
The liver synthesizes the majority of the cholesterol required by the human body (approximately 75%), meaning it is an endogenous substance that does not strictly need to be obtained from dietary sources.
Evaluate the given options
- "can not": Incorrect, as the liver is the primary organ responsible for de novo cholesterol synthesis.
- "can": Correct, as the liver possesses the metabolic pathways (HMG-CoA reductase pathway) to produce cholesterol.
