| Almost 50 years ago, the author noted that the rotatory dispersion of unfolded polypeptide chains depends on the concentration of denaturants. |
| The first separation is achieved by isoelectric focusing that separates protein polypeptide chains according to amino acid composition. |
| One such intervention involves the intravenous injection of secretin, a gastrointestinal polypeptide. |
| It is a basic protein with a single polypeptide chain and acts on cellular and model lipid membranes. |
| The LDL receptor is a polypeptide of 839 amino acids that spans the plasma membrane. |
| Vertebrate hemoglobins are tetrameric molecules comprised of two distinct polypeptide chains. |
