The structure given below is the constituent part of:
Correct answer: D. Proteins
- A. Lipids
- B. Carbohydrates
- C. Vitamins
- D. Proteins
Explanation
The picture represents an amino acid, which is the building block of proteins. Proteins are large, complex molecules composed of one or more polypeptide chains made up of amino acids linked together by peptide bonds. The sequence of amino acids determines the primary structure of the protein, which then folds into its functional three-dimensional structure.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
