- α‑Keratin is an intermediate filament with a basic structural unit of two α helices in a coiled coil. Each helix has a seven‑residue repeating unit (heptad repeat). A representation of the α helices of a coiled coil dimer is shown. Each letter represents a different amino acid residue.Both alpha keratin and collagen are fibrous proteins. However, the hydrogen bonding pattern is different between the helices of the respective proteins. What is the major difference?Compare and contrast structural features of collagen and α-keratin (OK to do this as a list or table comparing/contrasting 3-4 points, e.g. type of helices, noncovalent and covalent interactions between helices, favored residues). Can you please help?
