Polypeptides

Introduction to the Digestive System of the Human Body

Polypeptides are substances whose molecules consist of three* or more amino acids linked together by peptide bonds. (Note that the prefix "poly-" indicates "many", implying a structure consisting of multiple units attached together.)

For comparison:

  • Two amino acids linked together by a peptide bond form a dipeptide, whereas
  • Three or more amino acids linked together by a peptide bond form a polypeptide.
