    • Abstract


      The genesis of the collagen structure proposed by the Madras Group is briefly outlined. Recent crystal structure data on collagen-like peptides vindicate (i) the original proposal of Ramachandran and Kartha, namely, that the structure of collagen is a triple helical coiled-coil one, and (ii) the visualisation of the maximisation of hydrogen bonds directly or indirectly with water molecules, including Ca-H…O hydrogen bonds.
