| 1-letter code | The standard IUPAC single letter codes for each amino acid |
| 3-letter code | The standard IUPAC three letter codes for each amino acid |
| Full name | The IUPAC trivial name of each amino acid |
| Chemistry | Symbols indicating the chemical properties of each amino acid side chain |
| Abundance | The frequency of occurrence, expressed as a percentage, of each amino acid in all NP, AP and YP records in the NCBI Reference Sequence database as of January 17, 2006. |
| Side chain flexibility | A general description of the possible side chain motions caused by rotations about covalent bonds. |
| Molecular interaction modes | A list of modes in which side chain atoms may interact with atoms of other molecules including van der Waals interactions, hydrogen bonds, ionic bonds, and disulfide bonds. |
| Potential side chain hydrogen bonds | The total number of possible hydrogen bonds (both donated and accepted) involving side chain atoms |
| Residue molecular weight | The molecular weight of the amino acid residue incorporated into a polypeptide chain, which is equal to the molecular weight of the free amino acid minus the molecular weight of water |
| Isoelectric point | The pH at which the free amino acid is a neutral species (with no net charge) |
| Hydrophobicity | A normalized hydrobicity scale (Eisenberg, D. et al, J. Mol. Biol. (1984) 179:125) in which the most hydrophobic amino acid has a value of 1.000 and the most hydrophilic has a value of 0.0000. This is the same scale used in Cn3D 4.1. |
| Standard codon(s) | The RNA codons encoding each amino acid using the standard translation table. |
