Condensation Polymers

Polypeptides, Disaccharides and Polysaccharides

This post will go through condensation polymers: polypeptides, disaccharides and polysaccharides for QCE Chemistry.

4.2.3 – Macromolecules: Polymers, Proteins and Carbohydrates

• Describe the condensation reaction of 2-amino acids to form polypeptides (involving up to three amino acids), and understand that polypeptides (proteins) are formed when amino acid monomers are joined by peptide bonds
• Describe the condensation reaction of monosaccharides to form disaccharides (lactose, maltose and sucrose) and polysaccharides (starch, glycogen and cellulose), and understand that polysaccharides are formed when monosaccharides monomers are joined by glycosidic bonds.

Polypeptides
