A peptide having up to 10,000 amino acids is called as:
Correct answer: C. Polypeptide
- A. Dipeptide
- B. Protein
- C. Polypeptide
- D. Peptide
Explanation
OPTION A: When two amino acids are joined together, a dipeptide is formed. OPTION B: Proteins can be defined as polymers of amino acids or polypeptide chains. OPTION C: When several amino acids are linked together by many peptide bonds, the polypeptide bond is formed. Thus a peptide having 10000 amino acids is called a polypeptide. Hence, C is the correct option. OPTION D: A peptide bond links amino acids in a protein molecule to each other. The peptide bond is formed between a carboxyl group of one amino acid and an amino group of another amino acid.

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.
