Question 5
The formula that represents a protein is compound A. C₁H₂O₂ B. C₉H₁₁₄PN₈O₈ C. C₆₀₀H₁₀₀₀O₅₀₀ D. C₇₀₈H₁₁₃₀N₁₈₀O₂₂₄S₄
Worked Solution & Example Answer:The formula that represents a protein is compound A - VCE - SSCE Biology - Question 5 - 2006 - Paper 1
Step 1
Identify the correct formula for a protein
Answer
Proteins are large biomolecules composed of one or more long chains of amino acids. Their general formula can vary widely based on the types and sequences of amino acids. Among the provided options, we need to identify the formula consistent with the structure of proteins, which typically includes carbon (C), hydrogen (H), nitrogen (N), oxygen (O), and sometimes sulfur (S).
In this case, option D, C₇₀₈H₁₁₃₀N₁₈₀O₂₂₄S₄, contains all these elements in proportions that are representative of a complex protein, making this option the correct choice.
