Why are lipids harder to break down than carbohydrates?
Carbohydrates are broken down in digestion. Carbohydrates are easier to break down because carbohydrates are soluble in water, But on the other hand Lipids are much harder to break down because Lipids (fats) come in the form grease and oil. Grease is solid at room temperature, While oil is liquid. Fats require special digestive action before absorption because the end products must be carried away in a water medium (Blood and Lymph) in which fats are not soluble.
