📖 1. Carbohydrates Structure

🔑 Key Concepts & Definitions

• Monosaccharide structure: The fundamental unit of carbohydrates, typically consisting of a carbon chain with multiple hydroxyl groups and a carbonyl group (either aldehyde or ketone). "Monosaccharides are the simplest form of carbohydrates, characterized by their molecular formula (CH₂O)n and their specific stereochemistry" (source).
• Disaccharide formation: The process where two monosaccharides are linked via a glycosidic bond, resulting in a disaccharide. This involves a condensation reaction where a water molecule is removed. "Disaccharides are formed through glycosidic bonds between monosaccharides, which are critical for energy storage and transport" (source).
• Polysaccharide types: Large carbohydrate molecules composed of many monosaccharide units, classified mainly into storage polysaccharides (e.g., starch, glycogen) and structural polysaccharides (e.g., cellulose). "Polysaccharides exhibit diverse structures and functions, depending on their monomer composition and glycosidic linkages" (source).
• Carbohydrate stereochemistry: The spatial arrangement of atoms in monosaccharides, especially around chiral centers, which determines their specific…
