The liver acts as the body's central processor for the three main macronutrients: proteins, fats, and carbohydrates. It handles amino acids from proteins by deamination, uses carbon skeletons for energy or to make glucose, and converts excess nitrogen into urea for disposal. For carbohydrates, the liver stores glucose as glycogen and can release or generate glucose as needed through glycogenolysis and gluconeogenesis. In terms of fats, it oxidizes fatty acids for energy, can produce ketone bodies during fasting, and synthesizes lipids and lipoproteins for transport. Water is not a primary metabolic substrate of the liver, and while the liver stores vitamins and handles nucleotides to some extent, those aren’t the main metabolic duties. So, proteins, fats, and carbohydrates together best describe the liver’s metabolic roles.
