Definition of peptide in English:

peptide

noun 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 OCNH.
〔生化〕-OC-NH-肽；缩氨酸
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'.
