Lipids vs Carbohydrates

Advantages of Mammals storing Lipids rather than Carbohydrates

• Lipids produce more metabolic water when burned compared to carbohydrates.
• More energy is produced from lipids when they are metabolically broken down.
• Lipids are insoluble but carbohydrates are water-soluble. This is why lipids are not easily dissolved out of the cell unlike carbohydrates. This contributes to the phospholipid bi layer in cell membrane.
•  Lipids are more useful where insulation is required because it retains more heat.
• Lipids also protect delicate organs because they can be used as packing material around organs.
