Answer

Brief Explanations:

Amino acids have a general structure. They all contain an amino group (-NH₂), a carboxyl group (-COOH), and a variable R - group that gives each amino acid its unique properties. The other options list components that are not common to all amino acids. For example, phosphate groups are not part of the basic amino - acid structure, and five - carbon sugars and nitrogenous bases are components of nucleotides, not amino acids.

Answer:

an amino group, a carboxyl group, and an R group
