Peptide Science
Sequence
A peptide sequence is the ordered list of amino acids that make up a peptide or protein, written from the N-terminus to the C-terminus.
Detailed Explanation
The sequence determines the peptide's identity and function. Even single amino acid substitutions can dramatically alter biological activity. For example, the sequence of BPC-157 is Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val (15 amino acids). Sequences are typically written using three-letter or one-letter amino acid codes.
