During the oxidation of 1 g of fat, 38.9 kJ is released, and during the oxidation of 1 g of carbohydrates -17.6 kJ. Explain why the energy intensity of fats is 2 times higher than the energy intensity of carbohydrates. Use the chemical formulas of triglyceride and glucose for this.
In fats, carbon atoms are more reduced than in carbohydrates or proteins (in other words, in fats, more hydrogen atoms per carbon atom). Therefore, the oxidation of fats is more beneficial than the oxidation of carbohydrates and proteins.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
