Q1: Define carbohydrates and classify them with examples.
Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen in the ratio Cx(H2O)y. They are primarily synthesized by photosynthetic organisms and serve as energy sources and structural components.
Classification:
1. Monosaccharides (simple sugars; 3-7 carbons):
- Trioses (3C): Gly...
Q2: What are proteins? Describe the structure of amino acids and peptide bonds.
Proteins are polymers of amino acids; they are fundamental molecules performing diverse functions: enzyme catalysis, structural support, transport, immunity, regulation. Amino acid structure:
All amino acids have:
1. Carboxyl group (-COOH): Acidic group; donates proton.
2. Amino group (-NH2): Basic...
Q3: Explain the levels of protein structure with examples.
Protein structure has four hierarchical levels:
1. Primary structure:
- Linear sequence of amino acids in polypeptide chain.
- Held by peptide bonds.
- Example: Insulin has 51 amino acids in specific sequence.
- Determines all higher levels of structure; small changes (mutations) can drastically af...
