WebThe reaction between amines and carboxylic acids to form amides is biologically important. It is through this reaction that amino acids (molecules containing both amine and carboxylic acid substituents) link together in a polymer to form proteins. How Sciences Interconnect. WebEDC could react with carboxyl groups at a relatively narrow low pH range such as 3.5-4.5. If carboxyl groups were cyclizable, they would react quickly with EDC producing carboxylic anhydrides, which formed the corresponding amides when amine compounds were present.

WebIn the case of making amides from carboxylic acids, the difficulty comes because the carboxylic acid is a stronger acid (pK a ~5) than the ammonium salt (pK a ~10). The result is that there is very little amine and carboxylic acid at equilibrium. so there is very little nucleophile present. WebApr 1, 2024 · Getting a carboxylic acid to react directly with an amine is very difficult, that's why the body uses a huge ribosome to facilitate it. In a lab these couplings are also very complex, everything is protected apart from your target carb. acid and amine, which are then joined with coupling agents like DCC or HATU.
