What makes each amino acid unique?
What makes each amino acid unique?
The unique R group, or side chain, attached to the α-carbon atom determines the identity and properties of each amino acid.
How are amino acids classified?
How are amino acids classified?
Natural amino acids are grouped based on their polarity and the structure of their side chains. This classification helps understand their behavior in proteins.
What's special about amino acids in mammalian proteins?
What's special about amino acids in mammalian proteins?
Almost all amino acids found in proteins within mammals have a specific spatial arrangement. This chiral configuration contributes to their function.

Study Notes
Amino Acid Structure
- Amino acids have a specific structure, which is correctly described as having a central α-carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain (R group).
Classification of Natural Amino Acids
- The basis for classification of natural amino acids is the polarity and structural features of the side chains.
- Classification of natural amino acids can also be based on the metabolic fate of amino acids.
Amino Acids in Mammalian Proteins
- Amino acids found in mammalian proteins have a specific characteristic, with some exceptions.
α-Carbon Atom Configuration
- The α-carbon atom of an amino acid has an asymmetric configuration, except for glycine which has a symmetrical α-carbon atom.
- Glycine is the only amino acid that has a symmetrical α-carbon atom.
