Peptide sequence

A peptide sequence is the chain of amino acids that make up a given peptide. The sequence is generally read from the N-terminal end to the C-terminal end. It can be expressed by using the name of the amino acid (example: Glycine-Asparagine-Valine), a 3-letter abbreviation (Gly-Asn-Val), or more commonly, a 1-letter abbreviation (G-N-V).
