Q1: What are carbohydrates? Classify them and give examples of monosaccharides, disaccharides, and polysaccharides.

Carbohydrates: Organic compounds composed of carbon, hydrogen, and oxygen with the general formula Cn(H2O)m. They are polyhydroxy aldehydes or ketones and their derivatives. General characteristics: - Soluble in water (multiple OH groups) - Taste sweet (especially sugars) - Provide energy (4 kcal/g...

Q2: Explain the structure of glucose. Draw the Fischer projection and the Haworth structure. Discuss mutarotation.

Glucose (also called dextrose or grape sugar): Molecular formula: C6H12O6 Type: Aldohexose (6-carbon aldose sugar) Structural representations: 1. FISCHER PROJECTION (open-chain form): Shows the 2D representation of the 3D structure CHO | CHOH | CHOH ...

Q3: Explain amino acids. What is a peptide bond? Write the general structure of an amino acid and describe how proteins are formed from amino acids.

Amino acids: Organic compounds that contain both an amino group (-NH2) and a carboxyl group (-COOH) bonded to the same carbon atom (α-carbon). General structure of amino acid: Carboxyl group | v COOH | H2N-C-H (α-carbon) | R (si...
