Alpha helix: structure, bonding, and biological roles Alpha helix The alpha helix is a common protein secondary structure: a right-handed helical backbone stabilized by regular hydrogen bonds, important in enzymes, structural proteins, and membra…
Anfinsen's dogma: the sequence-driven view of protein folding and its limits Anfinsen's dogma Anfinsen's dogma (thermodynamic hypothesis) proposes that a protein's amino acid sequence determines its native structure; many proteins follow this, but chaperones, kinetics, and…
