Which of the following is not the name of an amino acid? A. Lysine

C. Methane

(Photo for proof at the bottom.)

Explanation:

All amino acids contain an amino group, a carboxyl group, and an R group. An amino group consists of NH2. A carboxyl group consists of COOH. And an R group usually consists of a hydrogen or carbon atom bonded to the amino acid. Methane only consists of CH4, which clearly does not meet the criteria of an amino acid.
