what amino acids are rich with collagen
Collagen contains specific amino acids â Glycine, Proline, Hydroxyproline and Arginine. These amino acids have a regular arrangement in each of the three chains of these collagen subunits. The sequence often follows the pattern Gly-Pro-X or Gly-X-Hyp, where X may be any of various other amino acid residues.ollagen contains specific amino acids â Glycine, Proline, Hydroxyproline and Arginine.
