Unlike carbohydrates and lipids proteins contain which element?
The answer to your question is: Nitrogen Explanation: Organic molecules that are part of living organisms are composed by Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulphur. The elements available in more quantity are Carbon, Hydrogen and Oxygen. Nitrogen is present in proteins and nucleic acids.
carbon, hydrogen, nitrogen, and oxygen. Explanation: each amino acid in protein contains four elements: hydrogen, oxygen, nitrogen and carbon mark me brainliest please! have a nice day!
d. nitrogen Explanation: There are 4 types of bio molecules named carbohydrates, lipids, proteins and nucleic acids. Carbohydrates and lipids are made up of macro elements like carbon (C), hydrogen (H) and oxygen (O). But proteins additionally have nitrogen (N) apart from having carbon (C), hydrogen (H) and oxygen (O). They have some sulphur also but only in minute concentration that too in only a few peptides which have sulphur containing amino acids like methione and threonine An amine group (NH2) which contains nitrogen and forms amide bond is an absolute necessity for existence of a protein. An amide bond form backbone of a protein molecule. So the most suitable option is nitrogen.
In addition to hydrogen, carbon, oxygen and nitrogen, proteins also contain sulfur (in the amino acid methionine)
