Homework Answers
The answer is :
A tripeptide contains three amino acid residues.
Peptides are polymers of amino acids.
explanation
When 3 amino acids are linked by 2 peptide bonds, the tripeptide bond is formed with double peptide bonds. Peptides are the short polymers of amino acids & are categorized according to the no. of amino acid units present in the chain.
hope it helps.

Which three statements about amino acids are true? Use this chart of amino acid structures for reference. Lysine has one stereocenter (chiral center). Methionine is a thiol. The Leu side chain does not form hydrogen bonds with other amino acids. The form of glycine used by the human body is D-glycine. Ser and Thr are polar amino acids. Proline has an overall charge at physiological pH (7.4).
