Enzymes belong to which class of compounds?

Options

A. Polysaccharides
B. Polypeptides
C. Hydrocarbons
D. Polynitro hetcrocyclic compounds

Answer

**Step-by-Step Solution:**

1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up biochemical reactions in living organisms. They are crucial for various metabolic processes.

2. **Classifying Enzymes**: To classify enzymes, we need to look at their composition. Enzymes are primarily made up of proteins.

3. **Defining Polypeptides**: Polypeptides are chains of amino acids linked together by peptide bonds. They can be short chains (up to 50 amino acids) or longer chains that fold into functional proteins.

4. **Identifying the Correct Class**: Given the options:
- Polysaccharides: These are carbohydrates made of sugar molecules.
- Polypeptides: These are chains of amino acids that make up proteins, including enzymes.
- Hydrocarbons: These are organic compounds consisting entirely of hydrogen and carbon.
- Poly-nitro-heterocyclic compounds: These are complex organic compounds that do not relate to enzymes.

5. **Conclusion**: Since enzymes are proteins and proteins are made up of polypeptides, the correct answer is that enzymes belong to the class of compounds known as polypeptides.

**Final Answer**: Enzymes belong to the class of compounds known as polypeptides.
