It is highly concentrate source of energy as it is highly reduced, largely anhydrous and yield 9 k calgm energy as compared to 4 k cal g of protein carbohydrate.Fat stores constitute 75 of energy reserve and protein stores 25. Glycogen is the smallest resource of stored energy. Metabolic fuel stores in 70 kg man areFat :15 kg 135,000 K cal Protein : 6 kg 24,000 k cal Glycogen : 0.2 kg 800 k cal.
