Lipids and carbohydrates are two types of essential organic compounds that have similar chemical compositions but differ in terms of structure, behavior, function, and food sources.
Basis of differentiation | Lipids | Carbohydrates |
Definition | Are water-insoluble biomolecules composed of glycerol and fatty acids | Are water-soluble biomolecules composed of carbon, hydrogen, and oxygen |
Composition | Major elements - C, H, O Minor elements - N, S | C, H, and O |
Solubility | Are hydrophobic and not soluble in water | Are hydrophilic and soluble in water, except polysaccharides |
