Problem: The Murchison meteorite that landed in Australia in 1969 contained 92 different amino acids, including 21 found in Earth organisms. A skeleton structure (single bonds only) of one of these extraterrestrial amino acids is shown below.Draw a Lewis structure, and identify any atoms having a nonzero formal charge.
