Identify the functional group / groups found in amino acid.

Options

  1. ACOOH
  2. BCH ₃
  3. CNH ₂
  4. DCOOH and NH ₂

Correct answer

D. COOH and NH ₂

Step-by-step solution

Amino acids are organic molecules that serve as the building blocks of proteins. The general structure of an alpha-amino acid consists of a central carbon atom (the alpha carbon) bonded to an amino group ( -NH ₂ ), a carboxyl group ( -COOH ), a hydrogen atom, and a variable side chain (R group). Therefore, the functional groups characteristically found in all amino acids are the carboxyl group ( COOH ) and the amino group ( NH ₂ ). Answer: COOH and NH ₂
