Abstract:
1. A polypeptide comprising a peptide unit represented by formula (1) below and optionally one or more units represented by formulae (2) to (3) below: wherein “m” denotes an integer of 1 to 18, “p” and “q” are the same or different, each representing 0 or 1, “Y” represents Pro or Hyp, and “n” denotes an integer of 1 to 20; “Z” represents a peptide chain comprising 1 to 10 amino acid residue(s), “r” denotes an integer of 1 to 20, and “R” represents a linear or branched alkylene group; the molar ratio of “a” relative to “b” [a/b] is 100/0 to 30/70; wherein the polypeptide shows a peak of molecular weight in a range from 60 kD to 1000 kD in the molecular weight distribution in terms of globular protein by means of an aqueous gel permeation chromatography, and at least part of the polypeptide forms a triple helix.
