Question
Which is found in amino acids?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Amino acids have a central (alpha) carbon atom bonded to an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a variable R group (side chain). So, all A, B, and C are found in amino acids.
Hint
Do amino acids have a central carbon, an amino group, and a carboxyl group?
