WebSep 25, 2024 · A peptide bond is a covalent bond that is formed between two amino acids. To form a peptide bond, a carboxyl group of one amino acid reacts with the amino group of another amino acid. As a result, a molecule of water is also released. This is referred to as a condensation reaction.
WebIn order to form a peptide bond a hydroxyl (-OH) is lost from a carboxylic group of one amino acid and a hydrogen atom is lost from an amine group of another amino acid The remaining carbon atom (with the double-bonded oxygen) from the first amino acid bonds to the nitrogen atom of the second amino acid candy crush 2796 suzy fullerWebIn prokaryotes, formation of a peptide bond during translation is catalyzed by (1 point) a.
