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).
