Name an essential amino acid with a sulfur-containing side chain.

Explanation:
Essential amino acids must be obtained from the diet because the body cannot make them. The one with a sulfur-containing side chain is methionine, which has a thioether group that includes sulfur. Leucine and valine are essential but have only hydrocarbon side chains, and lysine lacks sulfur as well. So methionine is the sulfur-containing essential amino acid in this set. (Methionine also functions as a methyl group donor in the body via S-adenosylmethionine, highlighting its unique chemical role.)
