The gene directs cells to make one protein molecule, which breaks into two smaller ones, called peptides.

Now generate sixty-four million diVerent small proteins, called peptides, say, six amino acids in length.

They join together to form short polymer chains called peptides or longer chains called either polypeptides or proteins.

This protein is an aminopeptidase, which is an enzyme that cleaves other proteins into smaller fragments called peptides.

These fragments are called peptides and allow for the identification of the protein with their characteristic mass and pattern.

Scientists call the substances peptide growth factors because they are proteins or short strings of amino acids called peptides.

The continuous stretch of amino acid residues in the chain that enables targeting are called signal peptides or targeting peptides.

They are called A-type, B-type, and C-type natriuretic peptides (small protein molecules).

Eventually he isolated two related, protein-like molecules called peptides that killed a variety of microbes.
