Definition of peptide in English: peptidenoun ˈpɛptʌɪdˈpɛptaɪd Biochemistry A compound consisting of two or more amino acids linked in a chain, the carboxyl group of each acid being joined to the amino group of the next by a bond of the type OCNH. Example sentencesExamples - Among the amino acids of the peptide, the most dramatic change was the Phe residue.
- The peptide contains complementary amino acid sequences, with alternating positive and negative charges.
- If there are only two amino acids then the peptide is a dipeptide.
- Transport of peptides and amino acids has been demonstrated in scutella isolated from barley, wheat, rice, and maize.
- These peptides are composed of amino acids, but are much smaller than proteins.
Origin Early 20th century: from German Peptid, back-formation from Polypeptid 'polypeptide'.
