Action of Heat on Amino Acids
Action of Heat on α-Amino Acids
α-Amino acids undergo dehydration on heating at 200° C to give diketopiperazine.
Action of Heat on β-Amino Acids
β-Amino acids lose ammonia on heating to form α,β-unsaturated acids.
Action of Heat on γ- and δ-Amino Acids
γ- and δ-Amino acids undergo intramolecular dehydration on heating to form cyclic amides called lactam.
