Answer Details
The element common to protein, carbohydrate, and lipid is hydrogen. Hydrogen is a chemical element that is present in all organic compounds, including the biomolecules that make up living organisms such as proteins, carbohydrates, and lipids.
Proteins, carbohydrates, and lipids are all made up of different combinations of carbon, hydrogen, and oxygen atoms. However, nitrogen and sometimes sulfur and phosphorus can also be present in proteins, while nitrogen can also be present in some carbohydrates.
In summary, while all of these biomolecules have unique properties and functions, they all contain hydrogen as a common element.
