To represent the 20 different amino acids, a system of codes has been established, with two commonly used formats: one-letter and three-letter codes. The one-letter code uses a single uppercase letter to represent each amino acid.
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. [2] Only these 22 appear in the genetic code of life. [3] [4]
Amino acids are organic compounds containing an amino group (-NH 2) and a carboxyl group (-COOH). This is the general structure of an amino acid: where R is the side chain functional group that distinguishes one amino acid from another. This is a table of the 20 amino acids derived from proteins.
There are 20 common amino acids. They are composed of C, H, O, N and S atoms. They are structurally and chemically different, and also differ in size and volume. Some are branched structures, some are linear, some have ring structures. One of the 20 common amino acids is actually an imino acid.
You can use either the single or multiple letter codes, but make sure to include braces if using the multiple code. You can also find symbols and molecular features of each natural amino acid in our Reference Table.
