Step 1: Understanding the Concept:
Biological macromolecules are polymers composed of repeating monomeric chemical subunits joined by covalent bonds.
Key Formula or Approach:
\[ \text{Amino Acid}_1 + \text{Amino Acid}_2 \xrightarrow{-\text{H}_2\text{O}} \text{Dipeptide (Peptide bond: } -\text{CO}-\text{NH}-) \]
Step 2: Detailed Explanation:
Proteins are high-molecular-weight biopolymers composed of chains of \(\alpha\)-amino acid monomers linked together by amide (peptide) bonds.
- Fatty acids and glycerol form fats (lipids).
- Glucose units form starch and cellulose (fibre).
Therefore, amino acids are the fundamental building blocks of proteins.
Step 3: Final Answer:
Thus, amino acids are the basic components of Protein, matching option (B).
