Osmora Scientific Glossary
Amino-acid sequence
The linear order of amino acid residues in a peptide or protein, read from the N-terminus (free amino group) to the C-terminus (free carboxyl group).
In plain language
The exact order of the building blocks in the chain — the thing that makes one peptide different from another.
Why it matters in research
Sequence defines a peptide's identity; two chains of the same length but different order are different molecules.
Where you'll encounter it
COAs, sequence listings, and identity discussions.
