Cambridge IGCSE Chemistry 0620 syllabus for exams in 2026, 2027 and 20282026–2028

Practise linking proteins to natural polyamides, amino acid monomers, hydrolysis and side-chain formula deductions.

How this is tested

  • state that proteins are natural polyamides made from amino acid monomers
  • link protein hydrolysis to amino acids and name acids or enzymes as reagents
  • deduce an R side-chain formula from relative molecular mass and shown atoms
