Question: How do carbohydrates differ from lipids?...
How do carbohydrates differ from lipids?
Solution
Carbohydrates are molecules that constitute more oxygen than fats and proteins and it needs only fewer molecules of oxygen for their oxidation. Carbohydrates are termed to be stored as glycogen in tissues for generating energy whenever required.
Complete answer:
Carbohydrates are more required for the generation of energy in the body than proteins and fats because carbohydrate molecules constitute relatively more oxygen than fat and proteins and consequently, they need fewer molecules of oxygen for their oxidation. Carbohydrates remain stored in the tissue in the form of glycogen for use in the production of energy, when necessary.
Now let us see difference between carbohydrates and lipids:
Carbohydrates | Lipids |
---|---|
Carbohydrates are divided into Monosaccharides, Disaccharides, Polyols, Oligosaccharides, and Polysaccharides | Lipids are divided into Fatty acids, Glycerolipids Glycerophospholipids, Sphingolipids, Sterol lipids, Prenol lipids, Saccharolipids and Polyketides |
4 calories of energy per gram of energy is synthesised in the human cells when metabolizing the carbohydrates | 9 calories of energy per gram of energy is synthesised in the human cells when metabolizing the lipids |
Majority of carbohydrates that are categorised are soluble in water, and are hydrophilic | Lipids are generally insoluble in water because they are hydrophobic |
Wheat, maize, rice, barley fruits and milk are natural sources of carbohydrates | Peanuts, cashew nuts, almonds, walnut, avocado, sunflower, flax, rapeseed seeds, legumes (soy), fish and sea foods are natural sources of lipids |
Note: Folate the kind of lipid rapidly loses activity over the periods of days and weeks, and also there is a significant loss of biochemical activity during harvesting, storage, processing, and preparation.
