Why Is G. N. Ramachandran Influential?
(Suggest an Edit or Addition)According to Wikipedia, Gopalasamudram Narayanan Ramachandran, or G.N. Ramachandran, FRS was an Indian physicist who was known for his work that led to his creation of the Ramachandran plot for understanding peptide structure. He was the first to propose a triple-helical model for the structure of collagen. He subsequently went on to make other major contributions in biology and physics.
