Tripeptide vs. Polypeptide — What's the Difference?

A tripeptide is a peptide derived from three amino acids joined by two or sometimes three peptide bonds. As for proteins, the function of peptides is determined by the constituent amino acids and their sequence.

A peptide, especially one composed of 10 or more amino acids.

A peptide containing three amino acids.

(organic chemistry) Any polymer of (same or different) amino acids joined via peptide bonds.

(chemistry) An organic compound formed from three amino acids joined by peptide bonds.

(biochemistry) Any such polymer that is not folded into a secondary structure of a protein.

(protein) A small protein containing up to 100 amino acids; see also oligopeptide.

A peptide containing 10 to more than 100 amino acids
