The covalent bond that joins two amino acids is why type of bond?

1 Answer

Amide bond


An amide bond is a type of ester bond formed when a carboxyl group (-COOH) reacts with an amino group (-NH_2). The resulting reaction involves the loss of a water molecule (dehydration) from the -OH of the carboxyl group and a hydrogen from the amino group. When a protein undergoes digestion, the amide bonds linking the amino acids are broken by specific enzymes with the aid of water.
