Question

Refer to the chart of amino acid structures to help answer this question. Which four statements about amino acids are true? Leucine has an overall charge at physiological pH (7.4). Phe can undergo oxidation to form Tyr. Isoleucine has more than one stereocenter (chiral center). The Val side chain does not form hydrogen bonds with other amino acids. Methionine is a thiol. The form of glycine used by the human body is D-glycine. Asn and Gln are polar amino acids.

Step 1

Leucine has an overall charge at physiological pH (7.4): Leucine is a nonpolar, hydrophobic amino acid with a neutral side chain. At physiological pH, it has no overall charge. So, this statement is false. Show more…
