About G.N.Ramachandran

  • One of the important discoveries made by GNR, as he was known, was to unravel the structure of collagen – a substance that is found in bones, tendons etc and is the most abundant protein found in animals.
  • Proteins are long strings of amino acids and the way they fold, we know today, is very important and an incorrect folding can lead to many disorders.
  • Every year, the Council for Scientific and Industrial Research awards the G. N. Ramachandran gold medal for excellence in biological sciences and technology.
  • Also, the Central Leather Research Institute houses the Triple Helix Auditorium, so named after GNR’s ingenious discovery of collagen structure.

About collagen

  • Collagen is an abundant structural protein in all animals. In humans, collagen comprises one-third of the total protein, accounts for three-quarters of the dry weight of skin, and is the most prevalent component of the extracellular matrix (ECM).
  • Twenty-eight different types of collagen composed of at least 46 distinct polypeptide chains have been identified in vertebrates, and many other proteins contain collagenous domains
