The attraction between water molecules creates tension and a very delicate membrane. Water striders walk […]
At what temperature do amino acids break down?
At what temperature do amino acids break down? One concludes that amino acids do not exist in liquid or gaseous form. They decompose endothermally, with heats of decomposition between −72 and −151 kJ/mol, at well defined temperatures between 185 °C and 280 °C. Does heat kill amino acids?
