Nitrogen is an essential component of:
Show Hint
- Proteins
- Sugars
- Carbohydrates
- Lipids
The Correct Option is A
Solution and Explanation
(1) Proteins: Nitrogen is an essential component of amino acids, which are the building blocks of proteins. Therefore, proteins contain nitrogen. This is the correct answer.
(2) Sugars: Sugars (carbohydrates) are composed of carbon, hydrogen, and oxygen, but do not contain nitrogen. Hence, this is not the correct answer.
(3) Carbohydrates: Carbohydrates, like sugars, consist of carbon, hydrogen, and oxygen, but lack nitrogen. Hence, this is not the correct answer.
(4) Lipids: Lipids mainly consist of carbon, hydrogen, and oxygen. Nitrogen is typically not found in lipids. Hence, this is not the correct answer.
Conclusion: The correct answer is Option 1: Proteins as nitrogen is an essential component of proteins.
