Roles Classification
Biological Roles:
human metabolite  Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).
fat-soluble vitamin (role)  Any vitamin that dissolves in fats and are stored in body tissues. Unlike the water-soluble vitamins, they are stored in the body for long periods of time and generally pose a greater risk for toxicity when consumed in excess.
