Lipids are an important element of the cell membrane. The structure is usually composed of a glycerol backbone.
Carbohydrates, it's very literal: are “hydrates of carbon” and possess the general structure of C(n)H(2n)O(n).
Lipid molecules comprise more energy per gram than carbohydrates: close to two times as much.
Carbohydrates are more readily ingested than lipids and discharge their energy more quickly.
Monosaccharides and disaccharides are water-soluble and are less complicated to move to and from storage places than lipids.
Animals manage to apply carbohydrates fundamentally for short-term energy storage, while lipids are applied more for long-term energy storage.
Carbohydrates are stored as glycogen in creatures while lipids are stored as fats. In plants, carbohydrates are stored as cellulose and lipids as greases.
Lipids have less impact on osmotic force inside a cell than complex carbohydrates.
